Lentil Burgers: Add olive oil to a hot pan over medium heat. Add onions and carrots and sauté until onions are translucent and carrots are tender. Add garlic and cook for 30 seconds longer.
Put onions and carrots along with the rest of ingredients in a food processor. Pulse to combine.
Put the mixture in the fridge for at least an hour. This will help to form the patties easier.
Bake at 400° for 20 minutes, then flip and bake for another 20 minutes. You could also fry or grill them, just flatten them down first so that they cook evenly. You may also want to make them smaller so they fit in a bun.
Roasted Garlic Mayo: Slice about 1/2" off the top of a head of garlic (the pointy end), exposing the cloves, and leaving the skin on. Put the garlic in aluminum foil and drizzle with a couple of teaspoons of olive oil. Repeat with the other head. Cover the garlic with the aluminum foil.
Roast for 40 minutes at 400° until tender. Let sit until cool.
With a fork, mash garlic. Add vegan mayo and mix well.
