Preheat grill to medium-high (about 425–450°F). Clean and oil the grates.
Whisk olive oil, lemon juice, salt, pepper, garlic powder, paprika, onion powder, oregano, and honey in a bowl.
Reserve 1 tablespoon of the marinade for finishing and set aside.
Pat chicken dry. Pound any thicker portions to an even 1/2-inch thickness.
Toss chicken in the remaining marinade until coated. Rest 10–15 minutes at room temperature.
Grill chicken, covered, 5–6 minutes on the first side without moving.
Flip and grill 4–6 minutes more, until the thickest part registers 165°F.
Rest 5 minutes off heat. Brush with the reserved marinade and slice to serve.
