Set the oven to broil.
Place the chickpeas into a medium bowl and smash with a fork or potato masher until chunky smooth. Set aside.
In a medium bowl, add the yogurt, hot sauce, garlic powder, apple cider vinegar, and season with salt and pepper. Fold in the chickpeas, celery, and onion, and stir until combined.
On a baking sheet, place two pieces of bread down. On each piece of toast, top with the chickpea mixture, then avocado, then carrots and then place the slice of cheese on top. Place in the oven and broil for 2 minutes or until the cheese melts. Once the cheese melts, garnish with sprouts and top with the other bread slices.
