Not the first time, but with enough repetition after the 3rd cook, must mention that this is a great fish cook that's fast, simple, and will keep your significant other and your doctor happy:
Orange Roughy Filets (usually found at Sam's, Walmart, Costco, in a bulk freezer bag----and DOES NOT SMELL FISHY!)
Let 'em swim in a mixture of olive oil and lemon juice and some garlic, and a good dusting of Tony Chachere's Original Seasoning (or equivalent Cajun spice mixture(?)) and then re-dust before putting them on your fish grid (pre-sprayed with PAM or oiled up some other way) direct at about 350-400. Done tonight with a few nice sticks of well-soaked apple wood. Yummers! About 10 minutes per side.
Adding to the smoke of the Southwest from every direction (and God bless the victims most directly affected!),
