Chili (or use your recipe):

2 tablespoons vegetable oil
1 onion, diced
2 jalapeños, seeded and diced (optional)
1 pound ground beef
2 tablespoons chili powder
1/2 teaspoon ground cumin
1 (28-ounce) can Ro-tel
1 (15-ounce) can black or pinto beans, drained and rinsed
Salt to taste
3 cups shredded Mexican blend cheese
Tortilla chips
Sour cream, salsa, guacamole, etc. for serving
Make chili. In a Dutch oven over, medium high, heat oil. Add onion and jalapeños, if using, and sauté until translucent, about 3 minutes. Add ground beef, use a spoon or spatula to break it up, then season with chili powder and cumin.
When ground beef is cooked through, about 5 minutes, stir in Ro-tel. Reduce heat to medium low and let simmer until thick, 45 minutes to 1 hour. Stir occasionally. Season with salt to taste.
Refrigerate chili about 30 minutes.
Heat broiler. Line a baking sheet with foil or parchment. In a bowl, stir together cheese and 1 cup chili. Spread tortilla chips on baking sheet in a single layer, then spoon chili cheese mixture over chips. Broil until cheese is melted and lightly browned, about 3 minutes. Serve with sour cream, salsa, guacamole and whatever else you’d like to have nachos with.
