In a large skillet heat water, white sugar, honey, red wine, and garlic until sugar is completely disolved.
Coat chicken cutlets with flour and add to sauce. Cover and simmer for 15-20 minutes.
Uncover, add sliced onion to skillet and simmer (uncovered) until chicken is tender and sauce has thickened (should gloop a bit when drizzled- but you can thicken it to whatever consistency you like best) and onions are caramelized.
Optional (and awesome) serving option: serve chicken with sauce over white rice.
