4 teaspoons low-fat mayonnaise

4 teaspoons Dijon mustard

1 cup trimmed arugula

4 (1/8-inch-thick) slices red onion

12 ounces thinly sliced deli turkey

2 apples, each cored and cut crosswise into 8 (1/4-inch-thick)  slices

1/2 cup (2 ounces) grated Havarti cheese

Coarsely ground black pepper (optional)
