One of my fave easy meals is adding cooked shrimp to pasta.
Dice up some peppers, onion, and tomato. Very lightly saute the peppers and onions along with some chopped garlic (I use the stuff from a jar that's already minced into tiny pieces), then add the shrimp in just long enough to warm them up but not cook them again (again with the rubber thing!) As you're doing this, cook the pasta as usual. Drain the water and put the pasta back in the pot. Add the shrimp/peppers/onions/garlic, as well as the tomatoes. Toss it all with some extra virgin olive oil and serve! Have some fresh grated parmagiana cheese and maybe some freshly ground black pepper handy.
Yum.
