Combine the olive oil, garlic and onion powder, salt and pepper in a large bowl until well mixed.
Add the chicken cutlets and coat thoroughly.
Heat a large cast iron skillet and cook the chicken (about 5 minutes per side) until fully cooked and golden brown. While the chicken cooks, make the glaze, see below.
Remove from the heat and top each chicken breast with mozzarella slices.
Put the skillet in the oven for a few minutes to melt the cheese.
Remove from the oven, and top with tomato slices, drizzle with glaze and sprinkle the basil.
Devour.
For the glaze
Add glaze ingredients to a small saucepan and heat over medium-low heat.
Bring to a boil, then simmer 2-3 minutes, or until glaze turns syrupy. Keep warm.
