Wash the tomatoes and sweet peppers. Peel the carrots, onions, and garlic, rinse and dry. Prepare the required amount of spices, chili sauce and oil.
Cut carrots, onions and garlic into small pieces. If you have a food processor, use it to chop vegetables. This way you will spend less time cooking.
Take a frying pan, heat it a little over high heat, add oil and add chopped onions, carrots and garlic. Reduce heat and fry for 5 minutes, stirring.
Cut the tomatoes into cubes; you don’t have to remove the tomato peel.
Place the tomatoes in the pan where the onions, garlic and carrots are fried and continue to fry over low heat.
Remove the green part and seeds inside from the pepper, cut into small pieces: cubes or strips.
Add the pepper to the vegetables in the frying pan. Mix well and continue frying for another 5 minutes.
Add tomato paste, chili sauce and basil to the vegetables. Stir the tomato paste well so that it dissolves and is evenly distributed throughout the vegetable mass. Simmer for another 7-10 minutes. Let the sauce cool and place the sauce in a serving bowl.
Serve the sauce in a sauceboat, garnished with herbs, with any side dish and meat.
