Make pico de gallo.
Mix the beef, spices and seasoning together in a bowl and shape into 4 burgers.
Preheat a skillet over medium-high heat with olive oil. Place each burger in the skillet to sear for at least 2 minutes before flipping it on the other side.
Let each flipped burger sear for another 2 minutes, then lower the heat and cover the skillet for 2 more minutes until the burgers are cooked through.
Place about a ¼ cup of shredded cheese over each burger, turn off the heat and cover the skillet again for the cheese to fully melt.
Spread a layer of sour cream on the toasted bread, a teaspoon of pico de gallo and top with the burgers, more pico de gallo, sliced avocados, sliced jalapeño, fresh cilantro, sliced red onion, tortilla chips, and any additional toppings.
