Wondering how to make nachos on a grill? These Loaded Grilled Nachos take summer grilling to a new level with the best vegetarian nacho toppings!
Heat a grill to medium heat.
Prep the veggies: Cut the bell pepper in half, top-to-bottom, and remove seeds and pith. Cut the stem off the jalapeños and use a paring knife to carefully remove seeds, leaving peppers whole. Cut the onion into quarters top-to-bottom, leaving the bottom root attached the pieces stay together on the grill. Place the peppers and onion into a bowl, then drizzle them lightly with olive oil and sprinkle with salt.
Grill the veggies: Place the peppers and onion directly onto the grate and grill for 6 to 10 minutes until charred and slightly tender, turning occasionally. Remove from the grill and use for topping the nachos (below).
Make the beans: Drain the pinto beans and add them to a small bowl with the salsa, olive oil, garlic powder, and kosher salt. Mash with a fork until all beans are mashed and the texture is similar to chunky refried beans.
Assemble and grill the nachos: Place the tortilla chips into a medium cast-iron skillet or grillable pan. Top the chips with the beans, then cheese, and then the grilled veggies. Place the skillet on the grill until the cheese is melted, about 5 minutes.
Load the nachos: Top the finished nachos with sliced green onions, sour cream, guacamole, and torn coriander leaves.
