I wish I had a better picture of this, but I don’t.
This comes from Moosewood Restaurant Cooks at Home. The recipe is available widely on the internet, but here is the general gist:
You cook red lentils or yellow split peas until tender in a small pot. This is the dahl. Meanwhile, in a large pot, you saute onions, ginger, curry powder, hot pepper, cumin, and sweet potatoes. Then you add water, cauliflower, red or green bell pepper and simmer until tender. Then you add fresh spinach, lemon juice, and the dahl.
It sounds like kind of a pain to make, but it really isn’t.
