Add half diced onion into mix. Mix well. (Some pre-cook the mixture for 10 minutes before inserting into the hollowed potatoes.)
Fill boiling pot with water. 1/8 cup of olive oil.
Put in remaining onions. Spice. Empty can of diced tomatoes. Add two cups of water. Start heating the pot on low flame.
