No time for shopping, chopping, and prepping dinner? Consider stopping by a make-and-take food business. For under $3 per serving, you assemble 12 ready-to-cook entrees in two hours or less by moving between stations, scooping and pouring precut ingredients into baking pans or heavy-duty plastic bags. Freeze now, cook later. No fuss, no muss, and, best of all, no cleanup. Any wonder the largest enterprise is called Dream Dinners?
