Preheat oven to 425ºF (220ºC). Rub the cut sides of peppers with oil. Place peppers cut sides down on a baking sheet. Roast in the oven for 15-18 minutes until softened.

Meanwhile, add lentils, quinoa, water, cumin, and some salt to a medium saucepan over medium-high heat. Bring to a boil, cover, reduce heat to low, and simmer until lentils are tender, about 18-24 minutes.

Mix chipotle powder and vegan mayonnaise in a small bowl.

Transfer lentil and quinoa mixture into the roasted pepper. Top with the avocado and chipotle crema. Serve.

Mix ingredients together in a bowl and serve.

If you want to prepare multiple servings in advance, you can shred the carrots and lettuce and slice the onion in advance and store them in the fridge in a ziploc bag or tupperware container so you just have to dice a little cucumber and tomato and add a little dressing the next time.
