I’ve been eating greek yogurt (18g of protein), Kefir instead of plant-based milk in smoothies (+8g protein), and my plant-based protein powder has 30g of protein. Upping use of high-protein tofu as well.
Also, while I’ve been vegetarian (lacto/ovo) for a good 10+ years, I’ve recently started trying collagen. The powder I use is 19g of protein. I’m double-minded about using collagen but exploring for the supposed health benefits and to diversify my protein source. If I can find a “humane” source, maybe it’ll make it ethically easier for me.
