1 tablespoon olive oil
1 pound mixed exotic mushrooms, trimmed
1/4 teaspoon kosher salt
3/4 teaspoon freshly ground black pepper, divided
1 1/4 pounds ground sirloin
4 (2-ounce) whole-wheat hamburger buns, split
1 small head radicchio, sliced into thin rings
How to Make It
In a large nonstick skillet, heat oil over medium-high heat. Add mushrooms and 1/4 teaspoon each salt and pepper, and cook, stirring, until tender and golden (4-6 minutes). Transfer mushrooms to a plate. Wipe out skillet; reserve.
With clean hands, form meat into 4 patties; sprinkle remaining 1/2 teaspoon pepper over both sides of burgers. Return skillet to medium-high heat; cook burgers until medium (5-6 minutes per side), or until a meat thermometer inserted in the center reads 160°.
Place 1/4 of the radicchio slices, then burgers, on bottom buns; divide mushrooms among burgers and top with other half of bun.
