I am not a big fish fan, so finding a fish recipe that I not only liked, but REALLY liked, was pretty amazing, and it's so easy, so here it is:
2 Halibut steaks (about 140g each, "dry" with paper towel)
Enough low-fat sour cream to lightly coat the steaks, with a bit of olive oil mixed in.
Crumble 5 low-fat saltine crackers
1 1/2 tbsp of low-fat Parmesan cheese
Shakes of basil, paprika, garlic, steakhouse pepper
Coat Halibut with sour cream and oil mixture, roll in crumb mixture, and bake for 10 min at 500 F.
For the amount of stuff I used, I figured out this was about 220 calories per piece.
