Wash all the veggies except the onions & wipe dry. Cut the Zucchini & Onions into thick 1/2 inch/1 cm rounds.
Chop the Garlic finely. Slice the Bell Pepper into long & thick strips. (Use any color. I used Orange).
Whisk the Olive Oil, Balsamic Vinegar/Dressing, chopped Garlic, Basil, Salt & Pepper together in a large bowl.
Add the veggies. Toss.
Cook the veggies in a preheated Grill for 2-3 minutes, keeping the crunch intact. Remove & place in a plate.
Spray the outer sides of the bread slices with nonstick spay. Place them in a plate. (Sprayed side down).
Arrange the sun dried tomatoes & the grilled veggies on one slice of bread (unsprayed side) followed by the shredded Cheese.
Top with another slice of bread. (Sprayed side up).
Grill for 5 minutes or until you get nice grill marks.
Place on a plate lined with paper napkins. Garnish with sliced Jalapeños & a sprig of Rosemary.
Make the other 3 sandwiches in the same ways.
Enjoy!
