Consider batch cooking high-protein foods like grilled chicken, canned tuna, and roasted chickpeas. You can prepare a large amount of grilled chicken breast, which contains about 30g of protein per 4 oz, and pack it into containers with vegetables. Alternatively, make overnight oats topped with protein powder or Greek yogurt for breakfast, giving you an additional 20g of protein. Use a simple blender to whip up smoothies with protein powder for on-the-go snacks.
