No "source" exactly, but special thanks to Garett for the base idea of the recipe. And the lentils.
Cut both ends from the avocado and peel off skin. Cut avocado in half to pit, and slice off flesh from seed into mixing bowl. Mash sliced avocado with manual eggbeater until creamy and even. Pour in salsa and mix, while adding onion, garlic, lentils and vegan cheese (optional), mixing as you go. Serve.
