I haven’t tried it but I think it would do fine.

I need to avoid soy for thyroid issues as per my ND, and so was wondering what you might suggest to replace the tofu-white beans maybe? Thanks so much for any advice in this specific recipe as well as just in general, as I see you do use soy a fair bit in your ingredients. I actually love tofu so a bit of a bummer-lol.

I haven’t tried substituting the tofu but I think you are right. Maybe some kind of white bean would work.

One of things I’ve missed since eating a plant-based, gluten- and sugar-free diet, is a frittata with veggies. Made this recipe yesterday and felt like I was eating a frittata, only even better. What I had on hand were: summer squash, onion, bell pepper, brussel sprouts,mushrooms, and just-picked tomatoes. Because I like spiced-up food, I used lots of Aleppo pepper, sumac, coriander. I don’t use purchased vegetable broth, to avoid the sodium and other add-ins, so I made a broth from locally made organic chickpea miso. Also used apple cider vinegar instead of wine vinegar. Delicious!

What can you substitute if you don’t wNt up use the tofu?

Jill Dalton July 31, 2021 - 10:34 am

I haven’t tried any substitutes but I think a can of some kind of white bean or garbonzo beans might work.

What can be used in place of the white wine vinegar please?

Jill Dalton July 31, 2021 - 10:33 am

You can use any kind of vinegar really. Apple cider vinegar would be the closest replacement though.

Very good. I made this for my family but they were not as keen as I was. I made a mistake and doubled the liquid aminos which I thought would ruin it but it did not. I would add more nutritional yeast as I tried a bit with some and that was more to my liking. I am transitioning from salt, sugar and fat laden diet so I feel my tastebuds are still adapting to a no salt, sugar or oil vegan diet. I am so thankful for your recipes and your generosity.
