Wow! I've never seen a purple pepper. Do you think you can pick a peck of them

Oh, I see it's just one plant.
What do you think they'd be good in? A dish with eggplant might let you hide the color. But then maybe you want to show them off. Besides thinking of stuffed peppers and salads I'm at a loss and neither of those choices are good enough for your purple peppers. I'll ponder all night for you!
I just wish I can get a few tomatoes from the garden. It's been so dry around here this year that it's been miserable gardening.
