Det Burgers

• 3 tablespoons vegetable oil
• 1 medium onion, sliced (about 1 cup)
• Eight 1 1/2-inch crimini mushrooms (about 4 ounces), sliced
• Kosher salt and freshly milled black pepper
• One 4-ounce can sliced, peeled green chiles, drained
• 1/3 cup pitted, brine-cured olives such as kalamata, sliced
• 1 1/2 pounds ground beef chuck or round
• 6 ounces Cheddar cheese, cut into 4 slices
• 1/3 cup beer
• 4 hamburger buns, split and toasted

1. Heat 2 tablespoons of the oil in a large skillet over high heat until hot.
2. Reduce the heat to medium; add the onion and cook, stirring occasionally, until softened, about 5 minutes.
3. Increase the heat to medium-high; add the mushrooms and cook, stirring, until the mushrooms have browned and the liquid they release has evaporated, 4 to 5 minutes.
4. Season the mushroom mixture with salt and pepper to taste and transfer it to a bowl; add the chiles and olives and set aside.
5. Wipe out the skillet.
6. Gently shape the beef into four 4-inch burgers; season with salt and pepper.
7. Heat the remaining tablespoon of oil in the skillet over high heat until hot.
8. Reduce the heat to medium-high, add the burgers, and cook 3 minutes.
9. Turn the burgers and cook 2 minutes.
10. Top each with a quarter of the chile mixture and a slice of cheese.
11. Add the beer to the skillet; cover and steam until the cheese has melted, about 3 minutes.
12. Transfer the burgers to the toasted buns and serve.
