Preheat your oven to 375 degrees F. Cook the quinoa according to package instructions.
While the chickpeas are cooking, let’s prepare the peppers. Wash the bell peppers. Slice the peppers in half lengthwise and discard the seeds and membranes from the inside of the peppers. Spray the inside of bell peppers with oil and sprinkle some salt and pepper. Set them aside.
In a large bowl, combine quinoa, chickpeas, green chilies, cheese, cilantro, cumin, garlic salt, onion powder, chili powder, salt, pepper, and lemon juice. Mix until all ingredients are combined.
Spoon the quinoa and roasted chickpea filling into each bell pepper groove.
Arrange the stuffed bell peppers in a 9×13 inch baking dish and generously sprinkle each bell pepper with extra cheese. Cover the peppers with aluminum foil.
Transfer the baking tray to the oven and cook for about 45 minutes or until the peppers are tender and the cheese is all melted and bubbly.
Garnish with chopped cilantro leaves, spring onions, and serve immediately.
