Tortilla pinwheels make the perfect appetizer when you're serving a large group of people, because they're easy to make and can be customized to please any crowd. Once you get the hang of making basic tortilla pinwheels, mix them up by using a variety of different meats, cheeses and toppings, such as olives, onions, bean sprouts or avocado slices.
Lay a tortilla on a flat work surface. Use a knife or the back of a spoon to spread a thin layer or ranch dressing, mayonnaise, mustard or the spread of your choice.
Place a slice of lunch meat on top of the dressing, then a slice of cheese and, finally, a layer of lettuce.
Roll the tortilla tightly to resemble a jelly roll. Cover the tortilla roll with plastic wrap and refrigerate at least two hours.
Remove the tortilla roll from the plastic wrap. Use a knife to slice the roll into 1/2-inch pieces.
Arrange the pinwheels on a plate so the ingredients inside are visible.
You may use whipped cream cheese in place of cheese slices. Simply spread the cream cheese over the tortilla, then top with meat, lettuce, dressing and other desired toppings.
