I like the Jordan Market on Westwood Blvd. They have lots of interesting Middle Eastern stuff, like cheap packages of dried herbs. Everything is clean and pleasant, the produce is always good, and the people are nice.
This meal shows off the sheet pan at its most versatile: The protein, starch, vegetable, and pan sauce all cook to perfection in the same pan. Look for a large apple so the slices retain some texture after roasting.
