Parmesan Garlic Squash

I have recently developed a love for squash.  This tastes really yummy as a side to pasta and many other dishes.

2-3 zucchini and/or summer squash
Butter
Garlic salt
Parmesan cheese
Freshly ground pepper

Preheat oven to 425. Cut zucchini/summer squash in thin slices and arrange half evenly in baking dish. Place thin slices of butter on top (to taste... I used ~1.5-2 tbsp total). Sprinkle generously with garlic salt, Parmesan cheese, and pepper. Layer the rest of the zucchini and squash and repeat. Cover with foil and bake for 15-20 minutes (until center of zucchini/squash is becoming clear). Uncover and bake 5 more minutes.
