Build a Simple Meal Planning System to Protect Work Energy

Act as an energy management and practical life systems coach. I want to build a simple weekly meal planning system that protects my cognitive energy by eliminating daily decision fatigue around food. I have [COOKING_TIME] available on weekdays and [WEEKEND_PREP_TIME] on weekends. My goal is [ENERGY_GOAL] (e.g. sustained afternoon energy, less mid-day crash, fewer unhealthy impulse decisions). Design a meal planning system covering: a Sunday prep ritual, a rotating 2-week meal template, fast weekday meal options for high-demand days, how to reduce grocery shopping time, and the link between specific food choices and cognitive performance.
