Nacho Cheese Sauce

I found the basic recipe for this sauce on the internet. But I added to it and the result is below:

3 tbsp butter
2 tbsp corn starch
1 can evaporated milk
2 oz cream cheese (cubed)
2 cups shredded sharp cheddar cheese
1/4 cup shredded monterey jack cheese
1 small can/bottle salsa or pico de gallo
paprika - enough for flavor

Melt butter and cornstarch over medium heat in a sauce pan. Sitr. When butter melted add milk and cream cheese. Stir until cheese melted and sauce incorporated. Then add shredded cheeses and stir until melted. Remove from heat. Add salsa/pico de gallo and paprika. Serve with chips.
