Cook the lentils: In a pot, combine 1 cup uncooked black lentils with salted water. Cook for 15-20 minutes or until tender. Drain and set aside.
Prepare the quinoa: Simultaneously, cook 2 cups of quinoa according to package instructions until fluffy. Set aside.
Sauté the sofrito: In a skillet, heat 2 tablespoons of olive oil over medium heat. Add diced red bell pepper, diced onion, and minced garlic. Sauté for 5-7 minutes, until softened. Transfer to a bowl.
Combine ingredients: Add the cooked lentils to the sofrito along with 2 cups of quinoa, 1 teaspoon grilling seasoning, ½ teaspoon Aleppo pepper, ½ teaspoon cumin, ½ teaspoon salt, ½ cup chopped cilantro, 1 flax egg (or 1 large egg), ½ cup vital wheat gluten, and ¼ cup garbanzo bean flour. Mix well and mash into a chunky dough consistency. Chill in the refrigerator for 10 minutes.
Form the meatballs: Using a scoop, form the mixture into 32 evenly sized meatballs.
Fry or bake the meatballs: To fry, heat 2 tablespoons of olive oil in a pan over medium heat. Cook the meatballs for 6-8 minutes until golden brown and cooked through. To bake, preheat your oven to 400°F (200°C). Spray a mini muffin tin or baking sheet with cooking spray, then bake meatballs for 30 minutes until firm to the touch.
Prepare the sauce: In a skillet over medium heat, whisk together 1 cup tahini, ⅓ cup lemon juice, ¾ teaspoon salt, 1 teaspoon turmeric, ⅛ teaspoon black pepper, 1 grated garlic clove, and 1 cup water. Cook for 3 minutes until warmed throughout.
Combine meatballs and sauce: Toss half of the meatballs in the sauce, heating for 3-4 minutes. Store the remaining meatballs for later enjoyment.
Garnish: Serve the meatballs with optional garnishes such as diced red bell peppers, chopped parsley or cilantro, and toasted or raw pine nuts.
