Cut the breasts in half horizontally to create 4 steaks in total. Sprinkle each side with salt and pepper.
Place flour in a shallow dish. Coat chicken in flour and shake off excess.
Melt most of the butter in a large skillet over high heat - hold back about 1 tsp for later.
Place chicken in skillet and cook for 2 - 3 minutes until golden. Turn and cook the other side for 1 minute.
Turn heat down slightly to medium high.
Make a bit of room in the pan and add garlic and top with remaining dab of butter. Stir garlic briefly once butter melts.
Add vinegar, soy sauce and honey. Stir / shake pan to combine. Bring sauce to simmer, then simmer for 1 minute or until slightly thickened.
Turn chicken to coat in sauce. If the sauce gets too thick, add a touch of water and stir.
Remove from stove immediately. Place chicken on plates and drizzle over remaining sauce.
