Grilled Veggie Sandwiches

I love grilling vegetables. Here is an adaptation of a veggie-tarian burger that we love!

2 portobello mushroom caps
1 small zucchini
1 small yellow squash
4 leafs spinach
4 sprigs arugula
1/2 avacado
2 T mayonaise
Tomato slices
2 whole wheat kaiser rolls
olive oil
italian seasoning
(mozz. cheese optional)

Directions:
1. Pre-heat grill.
2. Cut zucchini and squash in half through the skinny side. Create 1/4 inch slices out of the two halves.
3. Lightly spray/brush olive oil on mushrooms and zucchini/squash. Dust with italian seasoning.
4. Grill mushrooms and zucchini/squash for a few minutes per side until grill lines form on them and mushrooms get soft. Toast rolls.
5. Chop avocado and mix with mayo. Spread on bottom and top of each roll.
6. Layer spinach and arugula next, followed by veggies.
