My fav way to make green beans is using one of Madhur Jaffrey's recipes. You cut the beans into 1/8-1/4" slices. Make a sauce by processing onion, garlic, ginger, tomato and turmeric. Then you fry the sauce and add some ground spices (cumin, corriander). In a separate pan, heat some oil and add whole cumin and mustard until they pop. Then, add the green beans and the sauce. Lastly, add lemon juice and salt and cook covered for 1/h hour. Eat with chapati. I had this for dinner tonight (with some seviyan for dessert).
