Preparation -- 15 minutes

FINELY dice the onion, click here to read how to dice onions like a pro. CHOP up the three cloves of garlic, and finely slice the two jalapeño peppers. If you want the dish to be spicier, include seeds too, otherwise, remove them first from the jalapeño peppers.

WASH the small tomatoes and slice them in halves. HEAT UP the medium-sized skillet, add in 2 tablespoons of vegetable oil. When hot, add in 1 teaspoon of chilli powder and 1 teaspoon of cumin seeds.

Cook for 2 minutes to really let the flavours come out. ADD diced onion, chopped garlic and sliced jalapeño peppers. BAKE for another 5 minutes on medium heat.
