I use HEB often. I just hit the seafood section and buy a little of everything that is raw and un seasoned then take it home and blend it all together with a little spinach. You can then spead it out about 1/2 deep on wax paper and a cookie sheet and freeze it. After it freezes cut it up into cubes and the fish will go nuts!
i like that idea. think i'll go and pick some up. tim what type off fish are you using in the mix?
