Rinse and clean the Whole Crab (4). Cut the crab in half or quarters, depending on the size, with the legs still attached.
In a heavy bottom pot (like a Dutch oven), add 3-counts of Olive Oil (to taste) and heat to medium heat. Add the Garlic (3 clove) and cook until fragrant, about 45 seconds.
Add the crab, toss in the Olive Oil (to taste) and the garlic, and saute for 4 - 5 minutes.
Add the Pasta Sauce (2 jar). Bring to a boil, then reduce to a simmer, and allow to simmer for 45 minutes. Stir occasionally and maintain heat to prevent burning.
Just as the sauce has thickened and all of the flavors have incorporated, bring a pot of salted water to a boil. Boil the Spaghetti (8 ounce) according to package directions.
Serve the sauce over a bowl of pasta. Be sure to supply plenty of napkins, knives to crack open the crab legs, and a bowl to discard shells. Serve and enjoy!
