Chop the potatoes and carrot. Add a bit of turmeric powder and salt to the mix. Boil in water till it cooks.

Chop the onions and tomatoes.

Add oil, mustard and jeera in a pan and fry.

Add onions to fry. Fry till it becomes brownish in colour.

Add a tinge of turmeric powder, salt, chilly powder and tomatoes. Continue cooking for 5 minutes. (Alternately you can add garlic paste before adding the rest of the ingredients to the mix.)

Once cooked properly, add the potatoes and carrot. Add some water to make it into a curry.

Add garam masala in the end. Add a bit more salt to taste, if less.

You may make the Malabar porotta separately. But, being a bachelor, I just bought the frozen mix and heated it up.
