Supporting My Partner During Bar Prep—Meal & Stress-Relief Tips?

My partner is taking the bar at the end of July. During midterms and finals, I usually provide healthy snacks and consistent dinners. Since bar prep is longer, I plan to handle all house chores and ensure daily healthy meals to minimize distractions. We already eat well, but I want to make a solid meal plan with easy, nutritious snacks that don’t interrupt study time. What are your favorite healthy meals and snacks for intense studying? Any specific ways to lighten their load?
