I would also watch out for soy milk with added sweeteners such as vanilla or chocolate. I enjoy rice milk more, it's not as heavy to me and I buy a brand which is non-GMO. There are a ton of different dairy alternatives such as rice, almond, hemp (actually REALLY good), soy....check them out and find out which one you like the best.
There are a lot of veggie burgers out there that are loaded with a bunch of fillers, but there are a lot out there that simply have veggies and grains on the ingredients. Another thing to look for is veggie burgers that are loaded with cheese! BAD! Check the ingredients my dear!
Hope this helps.
