Whole Wheat Ciabatta Bread-we buy ours at a local bakery. You can use whatever crusty, hearty bread you like. We brushed our bread with balsamic vinegar and grilled it briefly before putting on our panini fillings.
Grilled Veggies-we used grilled zucchini, yellow squash, and onions. I brushed them with balsamic and grilled them on both sides for a couple of minutes.
I also added roasted red peppers, artichokes, fresh spinach leaves, sliced tomatoes, and fresh basil. Josh added turkey and cheese.
Place panini directly on grill. Use a heavy pan to press down the panini. Cook for a couple minutes. Flip sandwich and press again. Cook for another couple of minutes. It's that easy!
