Preheat oven to 425°F. Rinse and cut sweet potatoes into small 1 inch cubes. Toss with olive oil and a dash of sea salt and lay evenly on parchment lined baking sheet.
Bake for about 15 minutes, until soft and slightly golden.
Remove sweet potatoes from oven and set aside.
Line a sheet pan with tortilla chips trying to cover entirely. Layer sweet potatoes, tomatoes, corn, and beans onto chips.
In a small bowl, toss cumin, chili powder and shredded cheese together and then sprinkle evenly over nachos.
Switch oven setting to Broil on LOW. Place nachos in oven and broil for about 2-3 minutes or until cheese is melted. **It cooks fast so keep a close eye on the oven!
Remove nachos and top with jalapeños, cilantro, chopped green onion, Greek yogurt and any other desired ingredients! Enjoy!
