Blend the lentils in a food processor until they resemble ground meat, but not completely pureed. Transfer to a bowl.

Next, blend the onion, tomato, bell pepper, garlic, and mint in the food processor and mix them with the lentils.

Add the oats, mustard, apple cider vinegar, and spices to the mixture. Be careful with the salt because the vegetable powder mix also contains salt!

Place the mixture in the refrigerator for 20 minutes to firm up.

Shape into patties and place on a baking sheet lined with parchment paper. Bake at 400°F until they are browned and crispy, about half an hour!
