Have the dressing made, with the minced chilli pepper added to the dressing. You will be using about 1/4 cup of dressing. Start with 1/4 tsp of chilli pepper to taste. Add more as desired. Of course you can use more dressing.
Add the lemon juice and remaining butter and cook the shrimp 1-1/2 minutes more, depending on the size of the shrimp.

Other salad component options: shredded red cabbage, diced red pepper, sliced cucumbers, bean sprouts, thinly sliced carrot batons, chopped parsley or cilantro.
I like the 16-20 per pound size of shrimp. They have a meaty presence that makes this truly feel like a meal. But feel free to use the size you prefer. And if you don't want to use shrimp with the shells attached, you will need to reduce the cooking time.
I purchase my Old Bay seasoning, it is easy to find at any grocery store. But I did include a link in the blog post for a homemade recipe if you need it.
