Not with complicated, time-consuming ingredients, but foods that make eating simple, healthy meals much easier. "I love keeping frozen fruit — wild blueberries are my favourite — on hand for easy smoothies," Amy Gorin, MS, RDN, owner of Amy Gorin Nutrition in the New York City area, told POPSUGAR. "I'll keep other staples for quick breakfasts on hand, including nut butter, oats, hemp seeds, and chia seeds." You can apply the same logic for lunch and dinner (think: breezy salads).
