Cut fish into 4 pieces and season with salt and pepper. On a work surface, arrange 3 slices bacon so they overlap slightly. Place a piece of fish at one short end and tightly wrap with bacon, cutting off any excess bacon. Repeat with remaining fish and bacon.
Whisk together mustard, honey, vinegar, and cup grapefruit juice; season with salt and pepper. Gradually whisk in oil.
Heat a large nonstick pan over medium-high. Place fish, seam side down, in pan and cook until bacon is deep golden brown on all sides, about 9 minutes, turning occasionally. Toss frisee with dressing and grapefruit and serve with fish.
The frisee was unexpectedly pleasant. I loved the light, sweet taste of the dressing. My husband asked me to make it again. I definitely will.
I have to say, I swear by Everyday Food recipes, but this one just didn't do it for me. First, it was tough to keep the bacon wrapped on the cod while cooking. Also, you have to have the perfectly sized piece of fish to make the presentation look right (which I didn't). Once cooked, it tasted okay but nothing special. I made the vinaigrette and didn't think it stacked up at all to the other Food Everyday vinaigrettes I have tried. Overall, thumbs down for me...a rarity with these recipes though.
