Wash asparagus, dry in a clean dish towel. Line them up and cut off the tough ends.
Make sure cod pieces are very dry. You may have to dry them with a paper towel. Line cod pieces in a line down the center of the baking sheet.
Divide them evenly among each side of the pan, spray with your preferred cooking oil and then add seasonings (lemon pepper and garlic salt) to taste. (Honestly, I just lightly sprinkled them over all of the asparagus.)
