Used chicken breast instead of salmon again. Obviously much better with sun-dried tomatoes! Doubled the Cajun seasoning (and the pasta) again. My timing is still terrible but I held the chicken longer this time so it wasn't so overcooked.
finished in 25 minutes, with uneven color on top, a bit salty with 9g fine sea salt; very crumbly. Maybe at 325' thicker cookie in slightly smaller pan?
