Yeast free Asian sauces

Hello, my son,9, has been diagnosed with a bakers yeast allergy. He has to avoid vinegars, fermented sauces etc He also needs to avoid dairy as well. Just starting to work out some dinner and lunch ideas for him that he will eat that will also fit with the new restrictions we have to follow. He loves Asian cuisine but wondering if the gluten free soy sauces and other sauces still contain yeast? If anyone has any other great ideas for a suitable dinner ideas please advise! submitted by /u/Art_babes
