Lindsay, from The Lean Green Bean, has this great recipe not only for jelly but for PB & J cups! Check it out: http://www.theleangreenbean.com/?s=chia
I made this strawberry jelly this past weekend and LOVE it! You could really use any berry or combination of them. For the kids, I may add a little sugar though.
If you have never seed Chia Seeds, except for the Cha Cha Chia commercials, they are an amazing Superfood! These little seeds are packed with Omega 3 fatty acids - brain and heart health. Because of their make-up, they thicken the food or liquid they are placed in. So, instead of a sugar mixture to thicken this jelly, the Chia Seeds get the job done!
Place 1 cup of frozen berries in a glass bowl and sprinkle 2 Tbsp of Chia Seeds on top. Cover it and microwave it all for 2 to 3 minutes. Take it out and start mashing it like the picture below.
Once it is at a consistency that you like, put it in an air tight container in the fridge and it will continue to thicken a bit. Just lovely!
