Quick Italian Cheesy Double Beef Burgers

• In a large frying pan, heat a drizzle of olive oil over medium-high heat. • Cook beef patties, until almost cooked through, 4-5 minutes each side (cook in batches if your pan is getting crowded). Transfer to a lined oven tray. • Sprinkle Cheddar cheese over each patty. • Place bake-at-home burger buns on the same tray. Bake until cheese is melted and buns are warmed through, 4-5 minutes.

• Meanwhile, thinly slice apple (see ingredients). Thinly slice tomato into rounds. Thinly slice brown onion. • Return frying pan to medium-high heat. Add another drizzle of olive oil, if needed. Cook onion, stirring regularly, until softened, 5-6 minutes. • Reduce heat to medium. Add the brown sugar, the balsamic vinegar (for the onion) and a splash of water. Mix well and cook until dark and sticky, 3-5 minutes.
