1 tbls butter
1-2 avocados

1. Pound chicken with a meat mallet to about 1/2 to 3/4 inch thick

2. Place chicken in a container with the marinade and let sit for 30 minutes

3. Warm up grill and then grill chicken about 7-8 minutes on each side

4. Slice the onion and then saute the butter until golden brown and tender

We also melted cheese on the chicken for a little extra flavor.
