Add the diced onion to a saucepan with a splash of water and sauté until softened. Stir in the cooked lentils, BBQ sauce, smoked paprika and garlic powder. Cook over medium-low heat for about 5–7 minutes, stirring occasionally, until the lentils are hot and coated in the sauce.
Spoon the BBQ lentil mixture onto the slider buns and top with shredded cabbage.
These little sandwiches are smoky, savory and satisfying and the crunchy cabbage adds the perfect fresh bite!
Serve them with a baked potato, crispy baked fries, sweet potato fries or a side of fresh vegetables for a delicious and satisfying meal.
