First, make the quinoa. In a saucepan, saute the shallot and garlic in a little bit of olive oil until translucent.
Add the quinoa and broth and bring to a boil. Once boiling, reduce heat, cover and cook for 15 minutes until broth is absorbed. Stir in pepper to taste, lime juice, butter, and cilantro.
Add the beans to the quinoa and stir until heated through.
Meanwhile, begin to heat the tortillas one at a time by lighlty oiling a frying pan and placing the tortilla flat on the bottom. Cover with a sprinkling of cheddar cheese and cover the pan. Fry until the cheese is melted and the bottom is lightly browned.
Once tortillas are done, layer in the middle with a row of spinach leaves, quinoa mixture, feta cheese, and avocado. Add salsa if you want. Roll up like a burrito and enjoy! MAke sure you roll while the tortilla is still warm or else it will get stiff and difficult to handle.
