Start by chopping the vegetables. Now add a little bit of oil to a pan and turn the heat to medium, once the pan is hot add the onion and garlic and sauté these until the onion gets translucent.
Now add the tomato, garam masala and pepper flakes and let it simmer for a couple of minutes before adding the water, herbs and bell peppers. Now cook this until you’re sauce has reached a preferable consistency, I personally like it a bit thicker so I cooked it for about 15 minutes. Add salt and pepper to taste.
Serve this with some rice or bread.
