High-protein idea: Swap butter for 2 tablespoons of peanut butter or almond butter, which adds about 8 grams of protein to your meal. Since processed nut butters can be sneaky sources of sugar and other unhealthy ingredients, look for a super-short ingredient list (like the nut, and maybe some salt, according to SELF.com).

High-protein idea: Trade a 6 ounce nonfat yogurt for a Greek yogurt version to get in about 6 more grams of protein per serving (for a total of 14 grams). Make your breakfast even healthier by adding fiber-rich berries to naturally sweeten your meal, and sprinkle on seeds, nuts, or high-protein, high-fiber cereal to increase the amount of protein even more.
