Prepare the filling. Slice 1 onion and mushrooms finely. Fry with lemon.

Clean the fish through the back. To do this, make a cut on the back, release your fingers to the bone, cut with scissors, a bone's head and tail, remove it. Part of the intestines already removed, then take out everyone else inside. Remove the gills. Now beautiful fish. Wash it and dry it with a towel. Put in a baking dish. My fish did not fit, had her foil in the form to do. On the bottom of the form put the onions cut into rings, drizzle with the oil.

The fish on top grease with vegetable oil, sprinkle with breadcrumbs. Crackers is better to make your own from a loaf or cookie to large pieces.

Put into the oven for 20 minutes at 180 degrees. Help yourself. :-)
