Shrimp With Tomatoes And Garlic

Source: Unfortunately the original source has been lost. My recipe 
below makes considerable modificaion to the original.

1 T+ Olive oil
1 T butter
1 C chopped onion
4-6 cloves garlic, peeled and minced
1 C chopped pepper...green, banana, etc.
1 can diced tomatoes, undrained and finely chopped
1 t leaf thyme
1 t lemon juice
1 pound shrimp...can be pre-cooked or raw
Old Bay seasoning
JGM Mix 4+ (This is my concoction; see the recipe.)

Coat the shrimp with olive oil and the Old Bay seasoning and let sit until ready 
to use. Heat olive oil and butter in a large skillet. Add the chopped onion 
and sauté until the onion is soft.
Add the garlic and pepper, sauté another 5 minutes or so.
Add the tomatoes, thyme, and JGM Mix. Simmer for 10 minutes or so.
Add the shrimp. If the shrimp is pre-cooked, only allow them to come up to
temperature. If they're raw, increase cooking time until they are pink and curled,
about 5-7 minutes.
Sprinkle the cooking mixture with the lemon juice and stir. 
Serve over steamed or boiled rice.
Serves four.
