Step 1

Line a sheet tray with aluminum foil. Arrange the fries on the sheet tray in a single layer. Bake according to the package instructions. Season with salt.

Step 2

Heat the olive oil in a large cast-iron pan over medium heat. Add the onion and cook until softened, about 5 minutes. Add the garlic, chili powder and cumin and cook until the spices are fragrant, 1 to 2 minutes. Add the beef, salt and a few grinds of black pepper and cook, breaking the beef into bits while browning, until fully cooked, 8 to 10 minutes. Add the marinara sauce and stir to coat. Let cook for 5 minutes to let the flavors meld.

Step 3

Heat the nacho cheese sauce according to the package instructions. Top the fries with the chili and nacho cheese sauce, then garnish with the scallions and pickled jalapenos.
