Toast the low-carb bread slices in a toaster or under a broiler until golden and crisp.
Cut the avocado in half, remove the pit, and scoop the flesh into a small bowl.
Mash the avocado with a fork, leaving it as smooth or chunky as preferred.
Season with salt and pepper to taste.
Spread a layer of mashed avocado evenly over the toasted bread slices.
Top each slice with 2-3 tablespoons of cottage cheese, spreading it gently to cover.
Add any optional toppings like cherry tomatoes, fresh herbs, or a sprinkle of seasoning.
