Mix garlic powder and Mrs. Dash to enough lemon juice to marinate the filets. You can add to taste, but I recommend going a little heavy on the seasoning, especially the garlic.
Place the filets in the marinate and set 30 minutes. (Be sure to put them in the refrigerator during that time.)
While they are marinating you will need...
1 medium bowl
1 can of cold beer.
1/4 pound of butter.
1 jar of horseraddish.
Melt the butter in the bowl and spoon in a generous ammount of horseraddish.
Remove the marinated filets and place them on the grill...
(Here's the secret)
Place a few Basil leaves on the grill, then put the filets on the leaves, then more leaves over top of the fish.
When the basil leaves brown on the edges (about 4-5 minutes) then flip the filets, again so that they are laying on the little bed of fresh basil leaves.
4-5 minutes on the other side. Remember not to overcook the fish, the internal temperature should get to 145 degrees and the meat will turn a delecate white.
The basil will not stick to the fish, (although it adds a wonderful flavor) and this method of cooking prevents the fish from sticking to the grill.
Now, pour the butter and horseraddish sauce you made earlier over the walleye filets.
