Heat your oven to 375°F and grab a large baking sheet or oven-safe skillet. Spread the tortilla chips in a single layer—don't pack them too tight or they'll steam instead of staying crispy.

In a small bowl, mix the cooked chicken with the cumin, chili powder, and garlic powder. Drizzle with 1 tablespoon of olive oil and toss it around so every piece gets coated. This takes literally 30 seconds but makes a huge difference in flavor.

Warm the black beans in a small saucepan over medium heat for about 2 minutes. Stir occasionally so they don't stick to the bottom. You want them hot but not bubbling away—just warm enough to soften everything.

Scatter the seasoned chicken over your chips, then drizzle the warm beans across the top. Sprinkle the cheddar cheese evenly over everything you just laid down. I always use my hands for this because you get better coverage than trying to sprinkle from the bag.

Pop the whole thing in the oven for 5 to 7 minutes until the cheese melts and gets a little bubbly at the edges. Don't panic if it looks a little wet—it'll set up the second you pull it out. I burned my first batch because I walked away for 2 minutes, so keep an eye on it after minute 5.

Remove from the oven and immediately add the sour cream in little dollops across the top. Add the guacamole the same way, then scatter your fresh cilantro, red onion, and jalapeno slices over everything. This is when your loaded nachos 4th july crowd look actually Instagram-worthy.

Squeeze fresh lime juice over the whole thing and serve immediately while everything's still warm. The acid from the lime brings all the flavors together and keeps things tasting bright instead of heavy.
