👨🍳 Instructions
If using dry lentils, boil them in water for 20 minutes until tender, then drain. (Skip if using canned lentils).
Heat olive oil in a large pot over medium heat, sautéing the diced onions, minced garlic, and leftover chopped vegetables for 6-8 minutes until soft.
Pour in the cooked lentils and marinara sauce, reduce heat to low, and simmer for 15 minutes so the flavors meld together into a rich sauce.
Meanwhile, cook the pasta according to package directions, drain, and serve the hearty vegan bolognese generously over the top.
