It took me years to try Sunbutter, and like many above, required the assurance that I could get help from a loved one and/or medical personnel if needed. It is just too similar to peanut and nut butters. I think we bought one tub and it lasted over a year. Oddly enough, we eat a lot of it now (mostly my husband), but we make it from scratch: roasting and grinding safe sunflower seeds. (I still won't eat anything made with Sunbutter that I didn't make myself.)
Again, you don't need to add it to your diet unless you are trying to fill some nutrition deficiency that sunflower seeds can offer. Enjoy Life makes other granola bar flavours that taste good too. Libre Naturals granola bars are better, in my opinion.
Other healthy snack options: 'fudge babies' from chocolatecoveredkatie.com are pretty amazing and healthy too., seed and fruit trail mixes, granola, dried fruit, energy cookies, or even homemade granola bars.
If you plan on trying those granola bars, make sure you are in a place where you feel safe and have plenty of time, then reward yourself for trying something new. We are here for you!
Oh, and the answer turned out to be dark chocolate morsels in one batch and semisweet chips in the other.
