Set Foodi to 'saute' on high. Once heated, add vegetable oil and ground beef and brown until cooked through, about 3-5 minutes. Drain any excess grease and return beef to Foodi pot.
Add ground cumin, garlic salt, onion, bell pepper, and jalapeno pepper and saute for 2-3 minutes or until onion is translucent and peppers are able to be easily pierced with a fork. Turn off heat.
Add black beans to Foodi pot and gently stir until combined.
Sprinkle tortilla chips and then cheese overtop everything. Close the air crisping lid (attached) and set Foodi to 'air crisp' at 355 degrees Fahrenheit for 5 minutes, or until desired level of crispiness is reached.
Serve as is, or top with sour cream, green onions, fresh tomato, salsa, or your other favorite nacho toppings!
Notes
To make vegetarian: simply omit the beef. You can add more black beans or plant-based crumbles, if desired.
To make gluten-free: most tortilla chips are naturally gluten-free as they're made with corn, however, many are processed in facilities with wheat so be sure your tortilla chips are certified gluten-free.
Store any leftovers in an airtight glass container in the refrigerator for up to 3-5 days. I'll be honest, I don't love nachos leftover as the texture typically gets soft. BUT if you reheat them in your Foodi (air crisp for 1-2 minutes) or in a toaster oven/full-size oven they're usually pretty good. Just not as good as fresh. :)
