Instead of sun-dried tomato spread, spread the buns with basil pesto or pesto mayo. Just omit the chopped fresh basil.
Any sturdy bun, or a baguette sliced lengthwise, works well with this recipe.
Coleslaw, a marinated vegetable salad or pasta salad from the deli is a great choice to serve with these sandwiches.
Sun-dried tomato spread can be found near the Italian foods or in the deli section of your supermarket.
