A classic Frito pie is served right out of the bag but this family-size version is assembled on a baking sheet for easy serving. A quick stove-top chili is spooned over the chips and topped with sharp Cheddar, then broiled until nicely gooey. Even better, the homemade chili comes together in the time it takes to prepare your favorite toppings.
In a large, deep skillet, heat the olive oil over medium heat. Add three-fourths of the onion and cook, stirring occasionally, until just starting to soften, about 3 minutes. Add the jalapeño and garlic and cook, stirring occasionally, until the onion is softened and the vegetables are just starting to brown, about 5 minutes.
Add the beef and a generous pinch of salt to the skillet. Cook over medium-high heat, breaking up the meat with a wooden spoon or potato masher, until cooked through, 6 to 8 minutes. Add the tomato paste, chili powder and cumin and cook until fragrant and the meat is coated, 1 to 2 minutes. Add the strained tomatoes, chicken broth and beans. Bring to a simmer, then stir in the beans and simmer over medium-low heat until thickened, 10 to 15 minutes; season with salt and pepper.
While the chili simmers, shred the cheese and prepare your desired toppings.
Position the oven rack 6 to 8 inches from the heat source and preheat the broiler to high. Spread the Fritos on a large rimmed baking sheet. Spoon the chili evenly over the chips, then sprinkle the cheese on top. Broil for 1 to 3 minutes, until the cheese is bubbling. Top with the remaining diced onion and your choice of toppings.
