I did not soak the flax seeds.. I was in a time crunch.. next time I will grind up some of the seeds in my coffee grinder first- so there will be some ground some not- will let you know how that experiment goes.
Into the food processor
1 cup of flax seeds
1/2 of a small to medium red onion
1-3 cloves of garlic depending on your taste
lime juice from one lime
1/4 of dehydrated tomatoes reconstituted- save the water.

blend this up adding a bit of the constituted water if it is dry.. It will be a bit sticky but a firm dough.
I add a bit of flax seeds to the water that is left it gets gel like and a bit sticky- helping in the pressing out of the crackers.
On my dehydrator trays lined with teflex or parchment paper take a small amount- about 2 tsps and form into a ball- dipping fingers in the water to prevent sticking. press onto tray- forming a circle cracker- dip fingers in water when pressing down- press into the thinnest you can without making holes in the cracker. do this to all- I got about 40 crackers from this.. you could press into one sheet and score but I found it easier to get an even cracker doing it this way.
I sprinkled with a little more lime juice and a bit of celtic sea salt- put in dehydrator over night- at 110-115. This is a thin but sturdy cracker.. I just love them.
