Arrange the sweet potato slices on small-rimmed baking sheet and lightly brush both sides with olive oil. Bake for 20 minutes or until browned and tender.
Meanwhile, pulse the cottage cheese and avocado in a food processor until blended but slightly chunky. Add the green onion, lime peel and hot sauce.
Top the roasted sweet potatoes with the avocado mixture and garnish your favorite toppings. Toppings options include chopped cooked bacon, cherry tomatoes, fresh herbs, cucumber slices, micro-greens or sprouts, hard-boiled egg, black olives, or chopped bell peppers.
