Costco Items for Easy High-Protein Meals (Meal Prep Guide)

Costco items for easy high-protein meals are a game-changer if you want to eat well without cooking every night. Easy high-protein meals from Costco make it possible to hit your protein goals with minimal prep, predictable costs, and ingredients you can mix and match all week.

Here’s why this matters: higher-protein meals are consistently associated with better satiety and easier meal planning, especially for busy schedules.

Protein anchor + fiber-rich side + healthy fat
