• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut potatoes into 1⁄2-inch-thick wedges. Toss on a baking sheet with a large drizzle of oil, salt, and pepper. Roast on top rack until browned and crispy, 20-25 minutes.

• While potatoes roast, zest and quarter lime. Quarter mandarin orange. Peel and mince garlic. Halve buns.

• In a small bowl, combine mayonnaise, half the mustard, half the lime zest, 1 TBSP olive oil, 1⁄2 tsp sugar, 1⁄4 tsp Fajita Spice Blend, juice from one lime wedge, and juice from one mandarin orange wedge (for 4 servings, use all the lime zest, 2 TBSP olive oil, 1 tsp sugar, 1⁄2 tsp Fajita Spice Blend, juice from two lime wedges, and juice from two mandarin orange wedges). Season with salt and pepper.

• In a medium bowl, combine pork, garlic, remaining Fajita Spice Blend, remaining mustard, 1⁄2 tsp salt, juice from one lime wedge, juice from one mandarin orange wedge, and pepper (for 4 servings, use 1 tsp of salt, juice from two lime wedges, and juice from two mandarin orange wedges). Form into two patties (four patties for 4), each slightly wider than a burger bun. Swap in beef for pork.

• Heat a large drizzle of oil in a large pan over medium-high heat. Add patties and cook until cooked through, 4-6 minutes per side. • In the last minute of cooking, top each patty with Monterey Jack; cover pan to melt cheese. • Turn off heat; transfer patties to a plate. Wipe out pan.

• Melt 1 TBSP butter in the same pan over medium heat. Add buns, cut side down; toast until golden, 2-4 minutes. (For 4 servings, you may need to work in batches, using 1 TBSP butter for each batch.) • Spread bottom and top buns with a thin layer of sauce. Fill buns with patties and pickle slices. • Divide cheeseburgers and potato wedges between plates. Serve with any remaining lime wedges, mandarin orange wedges, and sauce on the side.
