Broccoli and Cauliflower Au Gratin

I made this last night for my son's 5th birthday party.  The picture above is the "pre-baked" picture, I forgot to take a picture after it was baked.  It was a hit at the party and fed about 10 people!

Ingredients:
Head of cauliflower
Bunch of broccoli
4 tbsp butter
4 tbsp flour
1 cup heavy cream
1/2 cup milk
1 cup shredded cheddar cheese
1/4 cup freshly grated Parmesan cheese
1 cup shredded Swiss cheese
1/2 tsp salt
1/4 tsp pepper
1/4 tsp paprika
1/4 tsp dry mustard
couple of red pepper flakes
2 cups of bread cubes (1/2" cubes)
olive oil
1 tsp parsley flakes
1 tsp garlic powder

Directions:
1.  Melt butter in saucepan over medium heat.  Stir in flour and allow to cook for a few minutes.  Slowly add milk and cream.  Allow to cook until thickened.
2.  Add all 3 cheeses, salt, pepper, paprika, mustard, and pepper flakes.  Cook on low-medium heat until all melted.
3.  In 9"x13" pan, put chopped broccoli and cauliflower.  Pour cheese sauce over vegetables and mix to combine.
4.  In a separate bowl, combine bread crumbs, parsley, and garlic powder.  Toss with Olive Oil until combined.
5.  Pour bread mixture on top of vegetables and top with a bit more of shredded cheddar.
6.  Bake at 375 for 45 minutes.
7.  Enjoy!

**Party Hint - I use disposal aluminum pans when I make large party foods.  It makes for extremely easy clean-up!**
