This original recipe was developed by Extenso—the Université de Montréal reference centre on human nutrition.


5 ml (1 tsp) canola oil
1 small yellow onion, finely chopped (about 125 ml / ½ cup)
3 garlic cloves, finely chopped
1 can (156 ml) tomato paste
1 can (796 ml) diced tomatoes
Salt and pepper to taste
Tabasco-style hot sauce (optional)


  1. In a large pot over medium-high heat, cook the onion and the garlic cloves in the oil for 2 minutes, or until browned.
  2. Add tomato paste and diced tomatoes. Add salt, pepper and hot sauce (if using).
  3. Bring to a boil, then lower heat and gently simmer the sauce.
    Add vegetables and a source of protein to the sauce. Beef, poultry, tofu and beans will taste great in the tomato sauce.
  4. Cover, leaving a small space for steam to escape, and cook over low heat for 30 minutes.
  5. Serve immediately with pasta or refrigerate for future use.
