"A simple vegetable dish that highlights the summer flavours of fresh tomatoes and zucchini. It goes great with grilled meats or poultry.
Ingredients:
- Zucchinis - 2 medium, thinly sliced
- Tomatoes - 5 plum, thinly sliced
- Cheddar Cheese - 1 1/2 cups, grated
- Parmesan Cheese - 1/3 cup, grated
- Garlicky Italian Seasoning - 1 Tbsp
- Salt & Pepper - to taste
- Butter - 1/4 cup
- Onion - 2 Tbsp finely chopped
- Fine Bread Crumbs - 3/4 cup
Instructions:
1) Preheat oven to 375 F. Lightly butter 9x9" pan.
2) In a large bowl, combine Cheddar, Parmesan, Garlicky Italian Seasoning. Season with salt and pepper, and set aside.
3) Arrange half of the zucchini slices in the pan. Sprinkle 1/4 of the cheese and herb mixture on top. Arrange half of the tomatoes, and top with another 1/4 of the cheese mixture. Repeat layers.
4) Melt butter in a skillet over medium heat. Stir in onions, and cook until soft and translucent. Stir in breadcrumbs; cook until they have absorbed the butter. Sprinkle on top of casserole.
