In a large mixing bowl, combine the cooked quinoa, cooked lentils, breadcrumbs, onion, garlic, tomato paste, soy sauce, dried herbs, salt, and pepper. Mix well until all the ingredients are evenly combined.
Shape the mixture into small meatballs, about 1-2 inches in diameter.
Heat olive oil in a large skillet over medium heat. Add the meatballs and cook until browned on all sides, turning gently to ensure even cooking. Remove from the skillet and set aside.
In a blender or food processor, combine the roasted red bell peppers, tomato sauce, vegetable broth, minced garlic, nutritional yeast (if using), salt, and pepper. Blend until smooth and creamy.
Cook the quinoa spaghetti according to the package instructions until al dente. Drain and set aside.
In the same skillet used for the meatballs, pour in the blended red bell pepper sauce and heat over medium heat until warmed through.
Add the cooked quinoa spaghetti to the skillet with the sauce and toss gently to coat the pasta evenly.
Serve the quinoa spaghetti topped with the vegan meatballs and garnish with fresh chopped basil.
