Every now and then we’ll splurge on some fresh crab at whole foods. Sometimes we just eat it plain, and sometimes there’s some extra with which to experiment. I know it is basic, but I still love a California roll, especially one with real crab.
You need:

-about 3-4 oz fresh crab

-about 2 oz plain Greek yogurt

-1-2 tbs green onion

-Black pepper

-2 seaweed wraps

-1 cup sticky rice of choice (I used a black rice/gf steel cut oat blend– oats make the rice sticky)

-1/4 cucumber slices

-1/4 avocado sliced 
Lay your seaweed sheet on a piece of plastic cling wrap, I put mine on top of a cutting board. 

The only trick I used is a line of water on each end of the nori wrap to help it stick together.

One by one, lay a nori sheet on a piece of plastic wrap (on top of a towel to make easier to handle, without plastic sticking to anything). Spread a layer of rice (actualy optional but recommended) to desired thickness over bottom 1/2 to 3/4 of wrap. Line up veggies/fillings. Spread a line of water (just dip your finer in water (along two ends of the wrap, and roll up, starting at full end and rolling towards empty end.
