- Healthy fats (10-15g): Promotes satiety and nutrient absorption
- Complex carbs (40-60g): Steady energy without crash
- Volume (500-700 calories): Large sandwiches that satisfy without excess calories

Meal Prep & Storage Tips
- Make components Sunday: Roast veggies, cook proteins, make sauces
- Layer smart: Wet ingredients (tomato, sauce) in center, dry ingredients (lettuce) on outside
- Wrap in parchment: Prevents sogginess better than plastic wrap
- Toast bread: Right before eating for maximum crunch
- Freeze extras: Hummus, pesto and bean mash freeze beautifully
