1 par-baked pizza crust (I used my sourdough bread recipe, with all white flour and made 2 crusts, baked for 10 minutes)
2 TB butter
2 TB flour
1/2 tsp mustard powder
1/2 cup milk
3 oz shredded cheddar
salt and pepper to taste
1-2 cups diced ham
1/2-3/4 cup frozen peas, defrosted
5 oz shredded mozzarella
Melt the butter over medium heat, whisk in flour and mustard powder and cook until bubbly. Slowly whisk in milk and cook, stirring constantly until thickened. Remove from heat and stir in cheddar until melted. Season to taste and set aside to cool.
Bake in 350 degree oven 15-20 minutes until cheese is melted and browned slightly.
Allow to cool slightly before slicing.
