This recipe is adapted from one of Martha Stewart's.

4 Tablespoons Butter
5 Medium zucchini
1 3 thick slices of a large onion
2 garlic cloves, minced
salt and pepper to taste
1/2 cup buttermilk
1 cup Panko bread crumbs
1 1/2 cups grated cheese (I used a mixture of mild Cheddar, Parmesan, Monterey Jack, and Mozzarella)

• Slice zucchini crosswise into 1/8 to 1/4 inch slices.

• Dice onion slices with a rough chop.

• Preheat oven to 450 degrees.
• In a large skillet, melt butter over medium heat.

• Add zucchini, onion, and garlic.

• Season with salt and pepper.
• Cook, stirring occasionally, until zucchini is crisp-tender (6-8 minutes)
• Add buttermilk.

• Cook until thickened, about 5-7 more minutes.

• Remove skillet from heat and stir in 1 cup of grated cheese.
• Stir in 1/2 Panko bread crumbs.
• Spoon mixture into a shallow 2-quart baking dish.

• Sprinkle remaining cheese and remaining bread crumbs over top.
