Houston's Spinach Artichoke Dip

There is a restaurant called Houston's that has the best ever Spinach Artichoke Dip. This is supposedly their recipe. My mom and I have been making for years as a dip to bring to a party. Sometimes we've even doubled the recipe (that makes ALOT) but it freezes well. Tonight I actually halved the recipe and made it for dinner two ways. One way, I diced some chicken and sauted it in a small skillet. I put the chicken in the bottom of a ramican and topped it with some of the dip. The second way was to split a chicken breast lengthwise and stuff it with the dip. I wrapped it in foil and baked at 375 for about 40 minutes. Here is the recipe for the dip. If you are bringing it to a party it traditionally served with corn tortilla chips.
