Haha, it has been hard! but it's like a super fun puzzle adventure to find substitutes for all of the stuff I love!
I've already found a great substitute for ice cream AND mac & cheese!! 😁
Take a look in my most recent post: https://steemit.com/keto/@abloveshorchata/keto-diet-part-3

I've also found a couple of websites that use peanut butter powder in some recipes... I love peanut butter, too, so I'm totally going to have to try one of those SOON!
And berries are fine, just in small amounts, so I'm SURE you could find a fun take on PB&J.

Thanks so much for your comment!
