Prepare Creamy Filling: In a mixing bowl, blend softened cream cheese and sour cream until smooth. Stir in garlic powder, onion powder, salt, and pepper.

Fold in Vegetables: Gently fold in diced bell peppers, shredded carrots, chopped green onions, and chopped spinach until evenly mixed.

Spread and Roll: Spread vegetable filling on a tortilla, roll tightly, and wrap in plastic wrap.

Chill: Refrigerate for at least 30 minutes to firm up the filling.

Slice and Serve: Unwrap and slice into 1-inch pinwheels. Arrange on a platter and serve.
