Meat and other related animal products are well-known for being efficient at providing the body with all nine essential amino acids. But as someone who is relatively new to eating a completely plant-based diet, I am struggling to find a variety of foods to incorporate into my meals to get an adequate amount of complete protein. I'd love to hear anything and everything from more experienced vegans about getting protein!

There are some products which are quite obviously animal-derived (e.g. leather), but there are a lot of others where it's much less obvious (e.g. tallow-based soap).

What are some of the less obvious places people might find animal-derived ingredients/products? Also, if you know of any good substitutes or alternatives to those, give your recommendations as well!

Meta note: wasn't sure where this would best fit in on the site, but I figured ~enviro is a good fit. If it needs to be moved to a better home, feel free!
