Mix together oatmeal and dry spices. Pour boiling water over and stir well. Stir in the mustard and let everything swell for about 10 minutes. If the mass is too dry at the end, simply add a little more water. If it's too wet, mix in a few more oats.

Form 4 schnitzels from the thick oatmeal mass with moistened hands. Roll them well in breadcrumbs.

In a large skillet, add enough vegetable oil to cover the bottom. Fry the schnitzel on both sides at medium temperature until golden brown. Be careful when turning and removing from the pan.
