Meal Prep Tips to Save Even More Time

• Batch similar tasks: chop all vegetables at once, cook multiple proteins simultaneously (sheet pans, oven space), and use one-pot or slow-cooker methods.
• Use durable containers: airtight glass or BPA-free plastic containers that stack well and are microwave-safe speed up weekday reheating.
• Label and date: write contents and date on containers to rotate through meals safely.
• Portion for success: single-serve portions make grab-and-go lunches and dinners easier and control portions.
• Keep fresh add-ins separate: dressings, avocado, and delicate greens are best packed separately and added at mealtime to preserve texture.
