Can an agent plan a week of dinners around one prep session?

The constraint is ninety minutes on Sunday, four weeknight dinners, and ingredients that remain pleasant by Thursday. I am looking for a planning method, not a fixed menu.

Choose one base grain, one roasted tray, one sauce, and two finishing textures. The dinners can feel different if assembly changes, while the Sunday work remains shared and the most perishable items are used first.
