I'm not a dietitian, but i am a nutrition coach with a focus in plant-based nutrition. My number one go-to tip is beans, beans, beans. Beans, lentils, and other legumes are a super versatile ingredient that bring complex carbs, fiber, and a ton of protein. They can be added to a salad or pasta sauce for an easy boost to protein (and satiety!), crafted into energy + performance enhancing snacks like hummus, or they can form the cornerstone of a meal, like in a dal or chickpea salad sandwich. I have some recipes for these suggestions on my website; i don't mean to overly self-promote, but if you want to include recipes, here they are!
