Plant-based vegetable sources are on the third level of both the vegan food pyramid. You should have at least one serving a day. This list here offers just a few suggestions to pick from, including meals containing good protein sources - of course, there are many more! The serving size depends on what you pick. For instance, one serving may be:
40-50 g raw or 150-220 g boiled legumes
50-100 g tofu, tempeh, or lupin products
Tofu sausages or cold cuts are okay, too, but try to prefer little processed products. If you are not gluten-intolerant, you may also eat seitan, however, since it contains the same amino acids as most foods from group 3 (starchy foods), it is preferable to eat legume products since they provide you with other relevant amino acids. Also, while seitan is high in protein, it is rather low in most vitamins and minerals.
If you think that cooking legumes takes a lot of time, remember that soaking them reduces the cooking time a lot and makes them easier to digest.
