Preheat the oven to 375 degrees F. Spray mini-muffin tins with cooking spray. Melt the butter in microwavable safe dish and stir in garlic salt. Set aside.
Place each wrapper into a section of a mini-muffin tin. Gently press each wrapper into the tin and arrange so that it forms a cup shape. The wrapper will overlap itself and stick up out of the cup. Brush insides with the garlic butter and bake for 8 to 10 minutes, until browned and crisp. (time may vary according to your oven, so keep a close eye on them) Remove from the tin and allow to cool while preparing salad.
Finely chop the romaine lettuce. If you have a food processor, use it. You really need a fine fine chop in order to fill the cups properly, so don't be lazy with this step!
Pour on caesar salad dressing and stir until all pieces are coated. Adjust dressing (adding more or less) to suit personal preference.
Spoon salad mixture into cooled wanton cups and sprinkle with freshly grated parmasan cheese. Bon Appetit! :).
