Cut the top from the green peppers and remove the seeds. In boiling water add some salt and put the green peppers in it. Leave it for 5 minutes. Then take them from the water and drain on paper towels.
Heat oil in a pan and fry the onions until golden and add mashed potatoes and steamed peas. Fry for few minutes and add red chili, turmeric, garam masala, cumin powders & salt and fry for 10 minutes. Add lime juice & put chopped cilantro before removing from heat.
Preheat the oven to 400F.
Keep the potato & peas mixture inside Green peppers and spinkle some grated cheese on top. Arrange the Green peppers in a greased baking tray. Reduce the oven heat to 375F. Bake the green peppers for 30 minutes or until cheese melts and top layer turns brown.
Filling Variation: Grind 1 1/2 big onion & 1 big tomato into a fine paste. Add 1 tsp of red chili powder, 1/4 tsp of turmeric powder, 1/4 tsp of black pepper powder, 1/2 tsp of garam masala powder, 1 tsp of ginger, garlic paste & salt and mix well. Stuff this mixture inside the green peppers. Heat oil in a shallow fry pan and carefully arrange the green peppers in it. Close the pan and cook over low heat for some time. Then turn the green peppers and cook until done. Serve hot. This filling would be a better choice with curd rice.
