Step 1
Pound or slice the chicken horizontally into 1 inch thick pieces. This will ensure they cook uniformly. Sprinkle with salt, pepper, and oregano on both sides.
Step 2
Heat the olive oil in a skillet over medium high heat. Add the chicken and cook for 3-5 minutes per side or until browned and cooked through. Remove and set aside.
Step 3
Add the garlic to the pan and cook for 30 seconds until fragrant but not burning. Add the tomatoes and bring to a simmer. Turn heat down to low and let simmer for 15 minutes, breaking the tomatoes up with a wooden spoon if desired.
Step 4
Add the butter and basil. Stir until butter melts. Add the chicken and cook 1-2 minutes while coating with the sauce. Season with salt and pepper if needed. Serve immediately.
