Chicken Fajitas

I don't measure out the ingredients exactly, but in the order of importance 
the marinade consists of:

Italian dressing
Worchester sauce
Garlic
Lemon Juice (Since moving to Texas, I have substituted a lime marinade sold by Kroger.  It has made it more flavorful)
Couple slices of Jalapeno Pepper (added since moving to Texas)

This is typically added to 4-6 chicken breast that are cut long and thin.

Grilled chicken

Both Ranch and Italian dressing make EXCELLENT marinades.
