There are several quick and convenient foods that are high in protein. One option is Greek yogurt, which typically contains around 15-20 grams of protein per serving. It is also rich in calcium and probiotics, making it a healthy choice for a snack or breakfast. Another great option is canned tuna or salmon. These fish are not only packed with protein (around 20-25 grams per can), but they also provide essential omega-3 fatty acids, which have numerous health benefits. They can be easily incorporated into salads, sandwiches, or even enjoyed straight from the can.
