Cheesy Chicken Sliders

1/2 cup vegetable oil

2 tablespoons Worcestershire sauce

2 teaspoons chili powder

3 cloves garlic, minced

Juice of 1 lemon

1 onion, chopped

Kosher salt and freshly ground black pepper

8 thin-cut chicken breasts, halved and flattened

8 Cheddar slices, halved 

Combine Worcestershire sauce, chili powder, garlic, lemon juice, onions and some salt and pepper in a bowl and pour into a resealable plastic bag. Add the chicken to the bag and marinate for at least 2 hours and up to 4. Grill the breasts for 2 to 3 minutes on the first side, then turn. Lay half a slice of cheese on each breast and grill until cooked through, a further 2 to 3 minutes.
