OK, these aren't baked, they're dried raw in the dehydrator. It's my new favourite thing. This excellent recipe is adapted from the Foods for Long Life blog. All this time I've been chucking the pulp from my juicer, now I'm freezing it to use later in crackers or baking.
There are 2 batches of crackers pictured here. I used carrot pulp in one and carrot/beetroot/apple in the other.

makes 60 crackers

1/2 cup flaxseeds
1 cup room temperature water

1/2 cup sunflower seeds, soaked for an hour
1 cup chopped, ripe, raw tomato [I used sundried tomatoes soaked for an hour]
1 tablespoon freshly squeezed lemon juice
1/2 teaspoon salt (or to taste)
3 cups carrot pulp

Mix flaxseeds with water in a large bowl and soak until all water is absorbed, about 4 hours.
When seeds are ready, process tomato, lemon juice and salt in a blender until liquified.
Add to bowl along with carrot pulp. Mix thoroughly. If too dry, add a touch of water.
Drop a measured tablespoon of pulp mixture on non-stick dehydrator sheets or baking paper and, with the back of a spoon, gently press down to form and shape round crackers. 
Dehydrate at 41C for 8 to 10 hours (can do this overnight). Flip crackers over, remove sheet, and place directly on mesh sheet. Dehydrate until crisp (another 6 hours or so). 
Remove and serve. Save in an air-tight container.

Crunchy, delicious and oh so healthy!
