1. Heat a large skillet over medium-high heat and add a tablespoon of olive oil. When the oil shimmers, add the diced onions and minced jalapeño. Sauté for about 3 minutes until softened and fragrant.
2. Add the garlic and cook for another 30 seconds, stirring constantly to avoid burning.
3. Add the ground beef to the skillet, breaking it up with a wooden spoon. Cook, stirring occasionally, until the meat is browned and cooked through, about 6-8 minutes.
4. Sprinkle in the ground cumin, smoked paprika, chili powder, salt, and pepper. Stir well to combine all the spices evenly. Let it cook for another 2 minutes, allowing the flavors to meld.
5. Reduce the heat to low and layer the slices of cheddar cheese over the meat mixture. Cover the skillet and let the cheese melt slowly, about 2-3 minutes.
6. While the cheese melts, lightly toast the hoagie rolls in the oven or on a griddle until golden and slightly crisp. This extra step was Mama Lou’s secret to balancing textures.
7. In a small bowl, mix the mayonnaise with lime juice for a zesty spread. Spread this on the inside of the toasted rolls.
8. Using a spatula, scoop the cheesy chopped beef onto the bottom halves of the buns. Top with diced tomato, shredded lettuce or cabbage, and sprinkle with fresh cilantro.
9. Place the top halves of the buns over the filling, press gently, and serve immediately while warm and melty.

One tip I learned from Ouma is to resist the urge to overfill the sandwich—it’s all about the perfect balance of juicy meat, melty cheese, and fresh toppings. That balance is what makes every bite a delight.
