For the cheese sauce:
- ¼ cup butter
- ¼ cup all-purpose flour
- 2 cups milk
- 1 cup shredded gouda or Swiss cheese
- salt & pepper
- nutmeg
For the casserole:
- 4 large zucchini
- 1 lb ground beef
- 1 small head of garlic roasted (optional)
- 1½ cups shredded cheddar cheese

For the tomato sauce:
- ½ cup olive oil
- ½ cup red onion finely diced
- 1 tbsp rosemary

Instructions
- Preheat the oven to 375°F (convection).
- To make the cheese sauce, melt the butter in a saucepan. Stir in the flour and cook briefly. Gradually whisk in the milk and bring to a boil, stirring constantly. Remove from heat and stir in the cheese. Season with salt, pepper, and nutmeg.
