Coat the bottom of a heavy pot with enough olive oil to cover the surface. Add the onion, and saute until very golden.
Add the vegetables (except greens), cooked beans, seasonings, salsa and tomato sauce. Adding water as needed for consistency, simmer until vegetables are almost desired softness (about 15 minutes) and then add the greens. Simmer another few minutes to wilt the greens. (Recipe♦101)
