Begin by cutting the corn tortillas into small pieces. You can cut them into quarters or smaller if you prefer. And heat a pot of oil to around 355-360°F (180-182°C) for frying the tortilla pieces.
Carefully add the tortilla pieces into the hot oil one by one to avoid sticking together. Fry until they are crispy and golden brown. You can fry in batches if needed
Remove the fried tortilla pieces and set them aside to drain on paper towels
In a separate pan, cook the ground beef until it's browned and cooked through. Drain any excess fat.
Add minced garlic to the cooked beef and sauté briefly, taking care not to burn the garlic.
Mix in chili powder to season the beef, stirring well to combine the flavors.
Add diced tomatoes to the beef mixture and continue to cook until the tomatoes are softened. Then stir in yellow mustard and mix thoroughly
Now, it's time to assemble the nachos. Place a layer of the crispy fried tortilla pieces on a serving platter.
Spoon the chili mixture over the tortilla chips, ensuring they are well covered.
If desired, you can add toppings like shredded cheese, sour cream, or diced green onions.
Your epic nachos are ready to enjoy! Serve them hot and savor the delicious flavors.
