Potato, Apple, and Cauliflower Cheese

Last month, I posted my cauliflower cheese recipe. A few days ago, I wanted to revisit it and to do something different with it. So I updated it by adding potato and apple, which varied the cauliflower taste. I also used only soy milk and no cream, and I added a hefty amount of mustard to the sauce. The result was quite tasty; it was still comfort food, but with a flavoursome zip to it.

I made so much that I filled two casserole dishes, so M and I will be eating it for lunch and dinner a couple of days in a row!

Ingredients:
1 medium cauliflower
2 baking potatoes
water for boiling
3 apples
75 g butter
1/3 cup flour
2 ½ cups milk (or soy milk)
175 g cheddar cheese, or other mature cheese, grated or chopped
2 tbsp whole-grain mustard
black pepper

Instructions:
1. Wash the cauliflower and the potatoes. Break the former into florets and cut slice the latter. Boil them in the water for about 10 minutes.
2. Slice the apples and set aside. Melt the butter in a saucepan and add the flour. Stir until mixed.
3. Add the milk. Stir.
4. Add most of the cheese and stir until it is a thick sauce.
5. Season with mustard and pepper.
6. Place the cauliflower, potatoes, and apples in one layer at the bottom of an oven-safe dish. Pour the sauce over it.
7. Top with the rest of the cheese.
8. Bake for 30 minutes at 200.
