This particular recipe has most likely been served to some of the most affluent individuals in the world. Kathy is mad because she can't cook, which is why she is on the internet looking for recipies.
I think I made it just as the recipe said, the shrimp were tasty, my green sauce looked like yours, and my bell peppers turned out well. We thought nothing went together. I might make grilled shrimp this way again (easy), and I am SURE I will make the stuffed peppers again, with the chopped ham, they were very good. But I would NEVER put these things together. And my sauce, though like yours, resembled a green sludge on the plate. Too much bell pepper going on. I recommend that others make the stuffed peppers as the recipe said, more as a good weeknight meal. Serve the grilled shrimp with other side dishes.
