Five weeknight dishes: Fast chicken fajitas, cod with caper-orange sauce and more

I recently wrote about a specific variety of cooking burnout: You don’t mind being in the kitchen, but you’re out of ideas for what to actually do in there. Several of you wrote in with your own antidotes, including digging around not for new ideas, but for recipes you used to love that you haven’t made in many years. (For me, Yotam Ottolenghi and Sami Tamimi’s chicken with caramelized onion and cardamom rice, from the cookbook “Jerusalem,” immediately springs to mind.)
