Princess Pasta

Wanted to celebrate Cinco De Mayo yesterday...
Kinda didn't get to the store...
This is so not Mexican, but is so yummy! With a name like "Princess Pasta", how can my girls refuse it?
2 tablespoons butter (or margarine)
1 tablespoon minced onion
4 ounces mushrooms, sliced
1/8 teaspoon salt
4 ounces of ham, cut in thin strips
1 tablespoon parsley, minced
1 pound short pasta (I use penne, mostaccioli works too)
1/2 pint whipping cream
1 cup grated parmesan cheese, divide 3/4 cup, and 1/4 cup for garnish

In a large pot, cook pasta according to directions on the package. While pasta is cooking, melt butter in a skillet on medium heat. Add onion and salt and saute until translucent. Add mushrooms. When those are cooked, add ham and parsley but remove from heat. Do not cook ham.
When pasta is done, drain completely and return pasta to the pot on medium heat. Pour in cream and stir until cream begins to bubble. Add 3/4 cup of cheese, and stir well. Remove from heat and add the ham/onion mixture. Garnish with some parsley and cheese.
Yummy!
