Ingredients
Main Ingredients
4 large bell peppers (any color), halved and seeds removed
2 cups cooked quinoa
2 ½ cups salsa
1 cup corn kernels
1 (15-ounce) can black beans, drained and rinsed
Spices and Seasoning
2 teaspoons cumin
1 teaspoon ancho chili powder
½ teaspoon smoked paprika
½ teaspoon garlic salt
¼ teaspoon salt
Toppings and Finishing
1 large or 2 small avocados, mashed
Juice of 1 lime
½ cup chopped fresh cilantro
½ teaspoon hot sauce (optional)
Water (as needed for thinning avocado topping)
Lime wedges, for serving
Instructions
Wash and prepare the bell peppers by cutting them in half lengthwise and removing seeds and membranes.
In a large bowl, combine cooked quinoa, salsa, corn, black beans, cumin, ancho chili powder, smoked paprika, garlic salt, and salt. Mix well until fully combined.
Spoon the quinoa mixture evenly into each bell pepper half, packing it gently so they hold their shape.
Place the stuffed peppers upright in the slow cooker. If needed, trim the bottoms slightly so they sit flat.
Pour a small amount of extra salsa or water at the bottom of the slow cooker to keep moisture during cooking.
Cover and cook on low for 4–6 hours or on high for 2–3 hours, until the peppers are tender but still hold their shape.
While the peppers are cooking, prepare the avocado topping by mashing avocado with lime juice, a pinch of salt, and a splash of water for a creamy consistency.
Once the peppers are done, carefully remove them from the slow cooker.
Top each stuffed pepper with mashed avocado, fresh cilantro, and a drizzle of hot sauce if desired.
Serve warm with lime wedges on the side for extra brightness.
Tips
Choose Firm Bell Peppers
Look for peppers that are thick and sturdy so they hold their shape during slow cooking.
Pre-Cook Quinoa for Best Texture
Using already cooked quinoa ensures the filling stays fluffy and fully cooked.
Don’t Overfill the Peppers
Lightly pack the filling so it heats evenly and doesn’t spill out during cooking.
Add Liquid at the Bottom of Slow Cooker
A small amount of salsa or water prevents burning and keeps peppers tender.
Keep Peppers Upright
If needed, slice a thin layer from the bottom so they sit flat in the slow cooker.
Adjust Spice Level Early
Taste the quinoa mixture before stuffing and adjust seasoning to your preference.
Use Fresh Lime Juice for Avocado
It keeps the avocado topping bright and prevents browning.
Add Avocado Just Before Serving
This keeps it fresh, creamy, and visually appealing.
Don’t Overcook on High Heat
Overcooking can make peppers too soft and watery.
Save Extra Filling
Any leftover quinoa mixture can be served as a side or salad base.
Variations
Cheesy Mexican Version
Add shredded cheddar or Monterey Jack cheese on top before serving.
Spicy Version

Mediterranean Twist
