Susan-
Here's a pizza crust recipe I've used for years ...

Disssolve:
1 1/2 c warm water
2 pkg yeast

Add 1 1/2 Tbspn sugar
1 1/2 tsp salt
1 1/2 Tbspn olive oil or canola oil

Add 2 1/4 cups flour
Add another 2 1/4 cups flour

Knead until well blended; can be used right away.
I usually half the recipe as the above make alot of crust!!
