Slice up one large lemon and line the bottom of the casserole.
Dump an entire bag of deveined and peeled shrimp (thawed) on top of the lemon.
Mix about 2/3 cup of olive oil with a packet of dried dressing mix (I've used both ranch and Italian) and pour over the shrimp.
Sprinkle shrimp with Mrs. Dash Garlic and Herb.
Bake at 400 degrees for 15 minutes.
You can eat as is or use in other dishes like I did last night when I removed the tails from the shrimp and put them in taco shells, topped with cheese, heated in microwave to melt cheese and then, topped with taco sauce and lettuce. It was DELICIOUS!!!
