American Cheese Sandwiches

1/2 lb American cheese shredded
1/2 lb bacon fried, drained, finely chopped (I use a lot more )
2 Tbsp (generous) chopped ripe olives
1 tsp chopped parsley
2 Tbsp finely chopped onions (I use a LOT more)
2/3 Cup mayo -- enough to hold it all together
1 doz dollar rolls split in half-- those small rolls from grocery

Flavor improves a bit if it's mixed a day before and stored in refrig. When it's about time to serve spread generously on each half of roll, set on cookie pan and bake at 350* about 8 minutes.
