Tofu is just as processed and packaged as any other processed/packaged food. It is made from soybeans, one of the most genetically modified and heavily sprayed crops on the planet. Roundup ready soybeans are GM'd to withstand heavy spraying so they are often covered in Roundup (an herbicide). It's pretty gnarly. Try to buy organic if you can!
Tempeh is fermented tofu. The type of soy most strongly associated with health benefits is fermented soy, commonly known as tempeh. You can slice it up and stir fry it, add some soy sauce and veggies. It's pretty good.
