That $15 takeout lunch costs $3 when you batch it. I’m a professional chef. Here’s the math: One Sunday prep gives you 5 restaurant-quality lunches for the week. Total grocery cost: $15-18. The system: → Roast chicken thighs (20 min, hands-off) → Cook quinoa once (15 min) → Prep veg while everything cooks → Portion into 5 containers Monday-Friday: Add sauce, heat 90 seconds, eat. No more decision fatigue. No more $75 weekly lunch tab. Just professional cooking systems for real life. Full breakdo
