           | There's many delicious and easy ways to eat vegetable! Two of
           | my favorite:
           | 
           | - Belgian Stoemp: basically smashed-potatoes with smashed-
           | other legumes. Cook everything together (with herbs if you
           | can), smash, add lipid and salt and you're done!
           | 
           | - German Ein Topf: put vegetables, beans and sausages in a
           | pot (I use tofu ones or tempeh). Cover, cook slowly. It's
           | almost a salty Tajin from the north.
           | 
           | - Recover bland vegetables (sprouts or anything) to a
           | fantastic soup in 5 minutes: add a bit of water, coconut
           | cream (or caw cream / silken tofu...), spices. A bit of tahin
           | and corail lentils if you have. Mix and adjust water.
           | 
           | Bon appetit :)

         | Great point about brussel sprouts and it's truly fascinating on
         | a number of levels. I think we're all tempted to believe the
         | story that our palate just changes as we get older. But that's
         | not what happened with brussel sprouts! They became cultivated
         | differently to change their taste and so the modern ones we
         | have are not the bitter ones we had as a kid.
         | 
         | I think there's a similar story for, say, canned peas which
         | used to be nasty and made me think I didn't like peas. Granted
         | I still don't consider myself someone who likes peas from a
         | can, but fresh peas in a salad, or flash frozen peas in a bag
         | that stores in the freezer, I'm open to those.
         | 
         | That's not to say that our tastes don't change, but brussel
         | sprouts are kind of a fascinating mirage where it seems like
         | the change might have been growing up into adulthood when
         | really it was a chang in cultivation. These are just off the
         | top of my head, but over the past couple of decades, there's
         | been a quiet revolution in mass produced veggies on a number of
         | levels that in each of their individual instances trace back to
         | fascinating stories of science.

       | 
       | Gai lan is just one variety of "Chinese broccoli" - there are

       | This doesn't mention the one brassica that I hate more than any.
       | Bastard cabbage. Like the other brassicas it is edible from
       | flower/fruit to the root. Goes good in salads, etc. Unfortunately
       | it is an invasive species here in Texas that quickly overwhelms
       | native wildflowers. It appears along roads where work has been
       | completed and rights-of-way reseeded using non-native grass
       | mixes.
       | 
       | It is native to Africa and southern Europe I think but is
       | invasive here in the US.
       | 
       | I first found some in my yard a couple of years after I bought a
       | load of "topsoil" from a local materials provider. Not only was
       | the product not a topsoil (it was river channel fine silt that is
       | mostly clay-like particles with zero permeability and zero
       | organic content) but the first thing to sprout on the pile of
       | left-over soil was a tall plant with yellow flowers. There was a
       | single plant that year. I had no idea what it was and asked one
       | of my kids to ID it after it had already dried. Since it wasn't
       | flowering stage when I asked they couldn't get a clear ID so i
       | left it in place. That was a huge mistake. It produced uncounted
       | quantities of small seeds that fell all around it and evidently
       | birds loved it.
       | 
       | The second year saw it sprout up in a 10m radius around the
       | original plant with isolated outliers. Again, I did not know what
       | it was so I let it grow until summer (it is a late winter/early
       | spring plant, one of the first to sprout) by which time it was
       | obvious that this thing was gonna take over if I didn't do
       | something. I sent a few more photos to my kid and this time I got
       | the bad news - bastard cabbage.
       | 
       | With that info in hand I began implementing my eradication plan.
       | I watered in all the plants that I could locate. It was summer
       | and the ground is very dry and soil is hard here at home. With
       | the soil nice and wet I pulled or dug every one of those bastards
       | that I could find knowing that I would be doing the same thing
       | again next year.
       | 
       | So far it has been several years of walking the property, pulling
       | these bastard cabbages as I find them. So far this year I have
       | less than a dozen plants but the season is young. I have found
       | about half of those plants growing where previously I had never
       | seen any and the others were growing in the original affected
       | area.
       | 
       | Just like my years-long battle against St Augustine grass,
       | stickers, goatheads, and Johnson grass I will win. I have
       | eradicated those plants from my property though it took more than
       | a decade to completely eliminate the Johnson grass.
       | 
       | Once I can identify the plant at each growth stage its days are
       | numbered, sometimes with three or four digits, but I will win in
       | the end.
