1. In a medium bowl, combine chicken, ham, mustard, and pepper. Mix until just blended. Form into 4 patties, about 4 inches across. Mixture will be sticky and may seem too wet, but it will firm up nicely as it cooks.

2. Heat a large nonstick skillet over medium-high heat. When hot, spray with vegetable cooking spray. Add patties to the pan. Cook until nicely browned, about 6 minutes, then flip. Cook an additional 6 to 7 minutes, so that chicken is completely cooked through. Alternately, cook on a preheated grill.

3. While the patties cook, toast the hamburger buns.

4. To assemble, layer romaine leaves and red pepper pieces on the bottom half of each bun. Top with patties and a slice of cheese. If desired, spread underside of each bun top with 1 Tbsp. mayonnaise, then place on top of patties.
