Pound the chicken breasts to an even thickness for consistent cooking.
In a bowl, whisk together olive oil, lemon juice, garlic, honey, Dijon mustard, paprika, salt, and pepper to make the marinade.
Place chicken in a resealable bag or shallow dish and pour marinade over top. Refrigerate for at least 30 minutes, up to 8 hours.
Preheat grill to medium-high heat and lightly oil the grates.
Grill chicken for 6–7 minutes per side, or until the internal temperature reaches 165°F.
Let rest for 5 minutes before slicing or serving.
