Instructions: Spruce up some purchased pasta salad with drained marinated artichoke hearts and marinated mushrooms for a hearty side dish. For dessert, spoon raspberries and sliced peaches over vanilla frozen yogurt.

Form beef into four 3" diameter patties. Form cheese into two 1 1/2" rounds; place cheese atop two beef patties. Top each with another beef patty, sealing at edges. Season with pepper.

Prepare barbecue (medium-high heat) or preheat broiler. Brush barbecue rack with vegetable oil. Grill burgers until charred outside but still juicy, about 3 minutes per side. Grill bread slices until lightly toasted, about 1 minute per side. Place each burger on 1 bread slice. Top with tomato, onion, arugula and another bread slice and serve.
