Preheat your oven to 350°F. Line a large baking sheet with parchment paper or aluminum foil for easy cleanup.
Take a large flour tortilla and cut it into a heart shape. You can freehand it with a knife, or use a large heart-shaped template as a guide. Don’t worry about making it perfect—rustic hearts are charming! You can make one giant nacho or several smaller ones.
Place the heart-shaped tortilla on your prepared baking sheet. Smother it generously with shredded cheese. The cheese is what holds everything together and makes it delicious. Cover the entire surface, going all the way to the edges.
Top the cheese with your favorite nacho toppings. Start with items that need to be heated (like beans or meat if using), then add fresh toppings like green onions, jalapeños, and tomatoes. Save delicate toppings like sour cream, guacamole, and cilantro for after baking.
Place the baking sheet in the preheated oven and bake for 10 minutes, or until the cheese is fully melted, bubbly, and starting to turn golden around the edges. Keep an eye on it. You want the cheese melted but not burned.
Remove from the oven and add your fresh, cold toppings. Dollops of sour cream, guacamole, extra tomatoes, cilantro, and a squeeze of lime. Serve immediately while it’s hot and the cheese is gooey.
