Weeknight dinners don’t have to be time-consuming to be delicious. In fact, sometimes the best meals are the ones that come together quickly, with minimal prep and maximum flavor. That’s exactly what makes these walnut and lentil baked tacos a weeknight winner. Packed with plant-based protein and veggies, they’re hearty, satisfying, and ready in under 30 minutes.

Most of the work happens in your food processor. Just pulse walnuts, onion, garlic, and bell pepper until they’re perfectly chopped. From there, a quick sauté in olive oil softens the veggies and brings out their flavor. Toss in some canned lentils and spices and you have a savory filling ready to go.

Layering the filling onto tortillas with a bit of melty cheese takes just a few minutes and a short stint in the oven ensures the tacos come out crispy. Pair these lentil baked tacos with some fresh salsa or guacamole for a delicious dinner the whole family will love.
