Cut one medium tomato, one grilled zucchini, and 10 oz cheddar cheese into slices.
Slice the baguette in half lengthwise. Spread ½ cup of homemade pesto on half the baguette, followed by four lettuce leaves, eight cheddar cheese slices, and two tomato slices.
Spread ½ cup of Chick-fil-A sauce and four slices of grilled zucchini on the other half of the baguette.
Combine both halves. Cut the baguette into half and serve.
