My Sunday chopping session is saving weekday dinners

I’m about three months into this chapter, and the scale is moving slowly. The real win has been a 40-minute Sunday prep: chop peppers and onions, cook a pot of lentils, portion Greek yogurt, and fill the water bottle I actually like. By Wednesday, when I’m tired and my appetite is weird, dinner isn’t a negotiation. Last night I made a real plate instead of grazing over the sink. I also left two bites behind without feeling deprived, which honestly shocked me. My partner calls the fridge "the salad museum," but it’s working. What’s the one Sunday task that makes your weekdays easier?
