Prepare the vegetables:

• Wash and cut the red bell pepper, eggplant, squash, zucchini, and red onion into thin slices.
• Place the vegetables on a sheet pan, and sprinkle with salt and pepper.
• Spray with olive oil
• Bake at 400 degrees for 10 – 12 minutes.

Prepare the cheese:

• Cut the havarti and gouda cheese into thin slices

Butter the bread:

• Spread a thin layer of butter or margarine on the outer side of each slice of bread. This will help achieve a golden and crispy crust when grilled.

Grill the sandwich:

• Heat a skillet or griddle over medium heat.
• Lay out the two slices of bread with the buttered side down into the pan.
• Evenly distribute the havarti cheese.
• Layer the sliced red bell pepper, eggplant, squash, zucchini, and red onion on top of the cheese.
• Evenly distribute the gouda cheese on top of the vegetables.
• Place the slices of bread buttered side up on top of the cheese-covered slices to create the sandwiches.
• Cook for 3-4 minutes on each side or until the bread is golden brown, and the cheese is melted.

Serve:

• Once both sides are grilled to your liking, remove the sandwiches from the heat.
• Let them cool for a minute before slicing.
• Serve hot and enjoy your delicious veggie grilled cheese sandwich!
