Ingredients

  • 1 cup dried lentils (green or brown)
  • 1 can (15 oz) black beans, drained and rinsed
  • 1 cup cooked quinoa
  • 1 block (14 oz) firm tofu, pressed and cubed
  • 1 large onion, diced
  • 3 cloves garlic, minced
  • 1 can (14 oz) diced tomatoes
  • 1 cup vegetable broth
  • 1 cup chopped bell peppers (any color)
  • 1 cup corn kernels (fresh or frozen)
  • 2 tsp chili powder
  • 1 tsp cumin
  • 1 tsp smoked paprika
  • Salt and pepper to taste
  • 2 tbsp olive oil
  • Fresh cilantro for garnish (optional)

Equipment

  • Slow cooker / Crockpot (4-6 quart capacity recommended)
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Mixing bowl for prepping tofu
  • Colander for rinsing beans and draining tofu
  • Wooden spoon or heat-safe spatula for stirring

Instructions

  1. Prepare the tofu: Press the tofu to remove excess moisture (wrap in a clean towel and place a heavy object on top for 15 minutes). Once pressed, cut into 1-inch cubes.
  2. Sauté aromatics: In a skillet, heat olive oil over medium heat. Add diced onion and minced garlic, cooking until softened and fragrant (about 3-4 minutes). This step enhances flavor but can be skipped for convenience.
  3. Add ingredients to slow cooker: Transfer sautéed onion and garlic to the slow cooker. Add lentils, black beans, diced tomatoes, vegetable broth, bell peppers, corn, chili powder, cumin, smoked paprika, salt, and pepper.
  4. Cook: Stir everything together, cover, and set the slow cooker on low for 6-8 hours or high for 3-4 hours. Lentils should be tender but not mushy.
  5. Add tofu and quinoa: About 30 minutes before the end of cooking, gently stir in the cubed tofu and cooked quinoa. This prevents the tofu from overcooking and keeps its texture intact.
  6. Final seasoning: Taste and adjust seasonings if needed. Add extra salt, pepper, or chili powder for more heat.
  7. Serve: Garnish with fresh cilantro if desired and enjoy your hearty, protein-packed slow cooker meal!

Tips & Variations

“For an even higher protein boost, add a scoop of your favorite plant-based protein powder or stir in some cooked chickpeas along with the lentils.”

  • Swap lentils for other legumes: Try using chickpeas, kidney beans, or black-eyed peas for variety.
  • Spice it up: Add diced jalapeños or a dash of cayenne pepper to increase the heat.
  • Make it creamy: Stir in coconut milk or a dollop of Greek yogurt (if vegetarian, not vegan) before serving.
  • Add greens: Toss in chopped kale, spinach, or Swiss chard during the last 15 minutes of cooking for added nutrients and color.
  • Use frozen veggies: Frozen bell peppers, corn, or mixed vegetables work well and save prep time.
  • Bulk it up: Serve over brown rice, cauliflower rice, or whole grain bread to round out the meal.
