I saw a video for simple sheet pan pasta dishes.

I had made something similar to the tomato based one years ago (the viral baked feta pasta thing). So, I decided to try the more unusual fennel, radicchio, and white bean recipe. However, I couldn't find radicchio and the fennel I did find was pretty anemic. He described radicchio (I've never had it) as a bitter cross between lettuce and cabbage. Bok choy sounded like a close enough alternative since it has a hard cabbage side and a leafy lettuce side.

I broiled everything like in the video. I especially liked the light charring on the bok choy leaves. I did find that it needed both cheese and lemon (he said one or the other).

I thought this dish was alright, but nothing to write home about. That's a weird phrase since I am literally writing about it... Anyway, I like the method and will try again with other combinations.
