Everything-crusted tuna with snap peas & tahini-jang sauce

This is my favorite dinner recipe from our most used cookbook for weeknights (Caro Chambers - What to Cook When You Don't Feel Like Cooking). The sauce alone is worth book. So easy and SLURPABLE. Searing the tuna is easier than I imagined, the snap peas cooked in the pan, delicious. Comes together in 15 minutes - no lies.
