Quick fish gratin

Because i cook with whatever i have around I used pre-cooked kale instead of spinach. Added two green peppers (cubed, sauteed briefly then cooked with the fish). I use lactose free evap milk. And used cheddar and gf all grain bread. Easy quick and very good! Also used a cast iron pan for stove top and broiler

I agree with previous review that it needs some more flavour. I tried original recipe but used panko instead of bread slice. Easy enough to make as week day dinner.

Add some mustard to the milk
