Peel and dice the onions and set aside. Cut bacon into small cubes.
Heat a little oil in a 9-liter pot and fry the bacon and onions until translucent. Add the minced meat and fry for a few minutes, stirring constantly. Cut the meat into small pieces. Douse with canned tomatoes, add tomato paste, spices and herbs and simmer on low heat.
In the meantime, peel the potatoes and carrots, cut into small cubes and add. Clean the leeks, wash them, remove the dark green ends and cut the leeks into fine rings. Wash, seed and finely dice the bell peppers and add them as well. Then cook until the potatoes are half soft.
Add the rice with some liquid and cook, stirring often. Keep adding water as needed to allow the rice to swell.
Season to taste with a few dashes of Tabasco and vinegar.
