A colorful,healthy sandwich which tastes great by itself or served along side a bowl of soup.Full of spinach,colored peppers and onions its a very nutritious sandwich. The pesto,cheese and jalapenos provide a very unique flavor to the sandwich.
Applying butter on the outside, gives a nice golden color and makes it crisp.
You can use any kind of hearty bread, I have tried it with Soudough, Multigrain,Ciabatta,Italian and Whole Wheat and they all taste great.
If you are grilling/cooking on pan then cucumbers,tomatoes and lettuce are not good options as they tend to get watery. if you are not grilling/cooking on pan the you can use Cucumbers,tomatoes and lettuce.
