Method:
In a large bowl, mix together beans, tomato, green onions, cilantro, cooked rice and cheese. Set aside.
In a small bowl, combine garlic and lime juice. In a slow, steady stream whisk in oil until dressing has slightly thickened. Add crushed red pepper and salt to taste. Stir lime dressing into bean mixture and season with hot sauce to taste.
Spread 1/4 of the avocado along the center of each tortilla. Top with bean mixture. Fold the edges up and roll up into burritos. Serve immediately, or heat on a baking sheet in a 350°F oven until cheese has melted and burritos are heated through, about 15 minutes.
