Making the best use of the ingredients you have on hand is one way to take the stress out of last minute entertaining. Pinwheel sandwiches are roll-ups that can use just about anything as a filling. Made with lavish bread or flour tortillas and cut crosswise into attractive wheels, these little sandwiches can fill in as appetizers or even full meals. You'll need a spread that will help glue the roll in place, a filling and possibly some veggies for color. Beyond that, the sky's the limit. How about cream cheese, thinly sliced purple onion and rare roast beef? Season the roll with a little ground chipotle pepper, and you're ready to dine.
