Slice the sweet potatoes crosswise into 24 (1/2-inch) rounds. Arrange on a large-rimmed baking pan. Brush both sides with the olive oil and sprinkle with the salt and pepper. Bake for 20 minutes or until lightly browned and tender.
Top with the cottage cheese, cranberries, and pecans. Drizzle with apricot preserves and sprinkle with rosemary.
