Drain skillet, wipe with paper towel and add duck fat. When hot, add bell pepper, leeks, garlic and cook until caramelized, 5-6 minutes. Remove to warm plate and cover with foil.
Brush grill with vegetable oil. Place patties on grill rack and cook, turning once, until done to preference, 5-7 minutes on each side for medium. Place cheese slices on patties during last 3 minutes of grilling. Place buns, cut side down on the outer edges of rack to toast lightly during the last 2 minutes of grilling.
To assemble burgers, mix vinegrette with salad and lightly toss. Place equal portions of frisee and 2 tomato slices on each bun bottom, followed by cheese topped patty, 1 slice pancetta and top with equal portion of caramelized leeks and pepper. Add bun top and serve.
