- Preheat oven to 375F.
- Chop up the fish, squash, and bell pepper into cubes (approx. 1-inch).
- Toss everything together in a large casserole dish.
- Bake uncovered for 35 minutes.
Substitutions: You can use any vegetables in this dish (just note that for root vegetables, you should boil or roast them for a while first as they will take longer to cook/soften). You can also use any fish and use any white spirit. I’ve also found balsamic vinegar to work well instead of apple cider vinegar.
