Easy Indian Flavors Veg

Being a bit worn down and only somewhat encouraged by media proclamations that one must eat more vegetable and fruits, I give you now this tasty, easy to do recipe.
Heat a sturdy pan with 1/4 c. vegetable oil. Toss in 1/2 tsp. of ground turmeric, mustard seeds, ground coriander and cumin seeds. Cook for 2-3 Min's, stirring. Add a sliced onion and a jalapeno pepper; include seeds if you like heat. Cook for 5-6 Min's. Get creative here; add cubed potatoes, cauliflower and the like. Cook until potatoes are somewhat tender. Add 1 or 2 cups of chopped tomatoes and continue cooking, covered, stirring until potatoes/cauliflower are softened; about 8 minutes Perhaps add, peas, garbanzo beans, broccoli, etc. Sprinkle in a wee bit of curry powder, salt, pepper, cayenne all to taste. Serve immediately over rice or couscous.
