Stir in carrot, basil, chili powder, thyme and sun-dried tomatoes and continue to cook for a couple of minutes. Remove the pan from heat and toss in the cooked or canned lentils.
Place half of the mixture in a food processor and the other half into a large bowl. Pulse the mixture in the food processor until most of it comes together and starts to break down.
Add the egg and continue to process until almost smooth.
Add the processed mixture, quick oats, 2 tbsp of tomato sauce and salt and pepper to the large bowl.
