The first move is to salt the raw slices on both sides and let the water come for a good amount of time and pat them dry. Then a good coating of EVOO and after oil then red wine vinegar. Grill them on both sides. Then toss them in a grill safe pan or tray and add oil a little garlic powder and onion powder and just them rock in there tossing them occasionally while you do the rest of your grilled items.
