Charcoal-grilled burgers with Mexican toppings like jalapeños and avocado are a street food hit. This high protein, family-friendly meal is a fresh, satisfying option for carnivore lovers.
Preheat a charcoal grill to medium-high heat, ensuring the coals are well ashed over for even cooking.
Gently form the ground beef into 4 equal patties, handling as little as possible; season both sides with kosher salt and black pepper.
Lightly brush each patty with vegetable oil to prevent sticking, then place them directly over the hot coals.
Grill patties for about 4 minutes per side, flipping only once for proper sear; adjust grilling time for desired doneness.
Lightly toast the hamburger buns cut-side down on the grill for 1–2 minutes until golden.
Spread mayonnaise on the toasted buns, add lettuce, grilled patty, avocado slices, tomato, onion, and pickled jalapeños in order.
Serve immediately while hot, assembling the burgers just before serving to preserve the bun texture.
