2 packages of frozen mixed broccoli and cauliflower

4 tablespoons butter

4 tablespoons all-purpose flour

3 cups milk

2 cups shredded cheddar cheese

1/2 teaspoon ground mustard

Salt and black pepper

Preheat the oven to 350 degrees Fahrenheit. Spray a 9 x 13-inch baking dish with cooking spray. Add the frozen vegetables to the baking dish.

In a saucepan over medium heat, melt the butter. Once the butter is melted, add the flour to the saucepan, and stir to combine. Cook for a few minutes to make a light colored (tan) roux. This will help thicken your sauce. Once you’ve reached a tan-colored roux, add the milk, cheese and mustard powder to the saucepan. Cook over medium heat until the sauce thickens to your desired consistency. Taste and season with salt and a few grinds of fresh black pepper to taste. Pour the sauce over the broccoli and cauliflower.

Bake casserole at 350 degrees Fahrenheit for approximately 50 minutes, or until the cheese sauce is nice and bubbly.
