I found this same recipe, minus the Tabasco sauce, somewhere on the web. It's really easy. Essentially you just sear, then cook some plain hamburger patties, then top with a pat of butter (I think it's a good idea to do this in the pan, so the butter can be soaked up when you toast the buns), and a little sauce made of (for each patty) 1/4tsp Worcestershire sauce, 1/8tsp Tabasco sauce, 1/2tbl lemon juice. Sprinkle on 1tbl chopped parsley. You might add a slice of onion. Extra yummy.

A yummy snack, definitely more-ish.

If you like things really spicy, you might consider bumping up the Tabasco sauce to 3 teaspoons or more. These are tasty, but not seriously hot.

Surprisingly good.
Our only criticism was that there wasn't enough Tabasco. Think the amount should be doubled (so a half recipe uses what's printed).
The bell peppers and Tabasco went surprisingly well together and didn't overwhelm the scallops. The capers added at the end we just the right touch of je-ne-sais quoi.
A keeper.
