I knew all I had to do was find someone to ask....
And the answer? I'm sure there are many answers.
The one I know is...
Tofu Tofu does not cause gas
And the other main ingredient in Tofu Dogs, pea protein
And lentils
Yeah, it turns out peas and lentils are rich in protein
And I used to eat pea soup and lentil soup all the time as a kid!
And what does cause sore stomachs? (I'm not surprised, cause protein is hard to digest)
Lots of meat!
Thank you, Sierra!
