First start by adding the ground beef and chopped onions to a fry pan and brown.

After browned add teh flour and milk until thickened.

Add 1 can each of beans, corn and tomatoes.

It should look like this. Put this filling in the freezer to cool while working on the dough.

In a large bowl combine the flour, salt and baking powder.

Mix it with your hands to distribute evenly.

Cut in the shortening, again using your hand until the dough looks crumbly. Add the milk, knead and roll out the dough (sorry no pics as flour was everywhere)

Spread the cooled filling onto the dough and roll it up.

Will sort of look like this.

Slice the roll up and place on greased baking sheets. Bake 20 minutes at 425.

Enjoy!
