1. I like to put swiss chard in lasagna. It's a vegetable that can be
used like spinach. Both red and green varieties are good. I don't know
if there is any major difference between them. If you are cooking red
chard with other ingredients though, the other food may turn pink!!
I usually separate the stems from the leaves before washing.
Stems: Rinse, chop, and put in pot of boiling water for a few minutes
to soften fibrous stems. (Or you could saute them)
Leaves: wash well and chop up a bit. Add to stems that have already
been cooking for a minute or two. When wilted, remove from
heat.
Strain chard to remove cooking liquid and add to one of the
lasagna layers. The stems add a nice bit of texture to the dish.
2. A veggie bolognese sauce is also good. I suspect that adding TVP to
any tomato sauce would work well. (I have a friend who used to add
bulgur to veggie chili to accomplish the same thing.)
