Hi I got a bunch of these a while back and used them as follows:
Teriyaki Shrimp
Make a marinade using 1/4 cup of soy, 3 tbsp of brown sugar, 1 inch stick of ginger minced, some finely chopped scallions, 1/4 tsp of sesame oil and a tiny bit of sambal (I like it spicy but you can leave it out).
Cook this until it's thick and reduced.
Take the shrimps and skewer it using a toothpick. Brush each with this thick sauce liberally. Place on a baking sheet and cook in a pre-heated over for 5-7 minutes. No one can tell they were made with pre-cooked shrimps and the shrimps don't get tough because you cook them not more than 5 minutes. I like to bump up my oven to 400 so it goes in and out fast
Another thing I have made with precooked shrimps is wraps. You can use a red onions (sliced thinly), assorted bell peppers and saute both of them quickly in a pan with a sprinkle or spray of olive oil. When the onions and peppers are soft throw in a chopped jalapeno, some lime zest and juice of a lime along with some cumin powder, salt and pepper (I also use garlic but you can omit it and you will not miss it). Stir in the precooked shrimps (discard tails and if they are large rough chop it) and shut the stove. Sprinkle some freshly chopped cilantro and scallions.
You can serve it inside any type of tortilla (even lowcarb) and serve it with a dollop of yogurt and salsa
Finally I love to make shrimp pilaf. You can cook your rice like pasta and drain and reserve it on the side (I only use Basmati). Next in a pan add a sliced onion and cook it until it's carmalized. Next add some minced ginger and spices (chili powder, turmeric, garam masala, bay leaf, corrainder and cumin powder). Now add assorted veggies (Frozen are fine - I like peas, carrots and french style green beans). Add a 1/4 cup of plain yogurt to this mixture. Ensure the veggie and spice mixture is not piping hot else the yogurt will curdle. First add the frozen veggies to bring the temperature down and then add the yogurt. Stir it all to combine. Add the shrimps and some freshly chopped mint and cilantro.
Layer the pilaf in a pan. First a spray of oil, followed by some rice, followed by the shrimp and veggies mix and then some more rice. Allow it to steam for 30 minutes on low heat until the flavors come togther.
Serve with some raita - I like to make mine with a cup of plain yogurt, 1 Shredded cucumber (discard the skin, seeds and liquid), salt and black pepper. Stir it all together.
