Five-ingredient hype is usually bland, so keep it stupid simple. Dump chicken thighs in a pan with a jar of salsa and a hit of cumin, roast until shred-friendly. Stuff into tortillas with a fist of shredded cheese and call it dinner.
Make it boring. Draw the same mug or your hand every night for 20 minutes. Date the page and toss it in a shoebox. Motivation is the pile getting heavier, not fireworks.
Two rules keep me on track... Cook once and package two meals, one for now and one frozen. Sheet pan dinners with a protein and mixed frozen veg prevent chopping. I portion rice or quinoa into flat freezer bags so they thaw fast. I buy half loaves and mini yogurts to stop half-eaten containers.
