Preheat oven to 350 degrees
Drain and rinse beans, and place in food processor
Pulse until beans are broken down, leaving them slightly chunky
Transfer beans to a large bowl and mix in cottage cheese, hot sauce, ranch dressing, 1 cup cheese and seasonings. Combine well
Transfer to an 8-inch baking dish and top with remaining cheese
Bake for 25-30 minutes, then turn oven setting to broil for 5 minutes so cheese on top fully melts
