Ingredients

3/4 lb. Beans/Carrot/Snow peas/Asparagus/potato/etc
note: Cut them into small pieces (grate carrot/beetroot - optional)
1/3 onion cut into small pieces
3/4 tsp. crushed red chile

oil
salt
mustard seeds
curry leaves (optional)
garlic (if you like; crush them)

Method

This is a stir-fry. Heat oil, add mustard seeds (if you are using it), then add onion (and garlic if you are using it), stir until it turns light brown, add salt, and then crushed chile; stir well for a while until the chile is well fried (mookkunnathuvare). Then add veg., stir well, cover it and cook in a low flame, and it is ready! (You can cook parippu, cherupayar, vanpayar, kadala, etc. too the same way. First you have to cook (boil) them, and add salt to
it when cooked. Also to the split peas and cherupayar, you can add 1/2 cup of shredded coconut, after frying crushed chile, if you like. When cooking kadala, you can add a teaspoon of garam masala too if you like, after adding crushed chile.)
