Cook bacon, drain, crumble and set aside.

In a large mixing bowl whisk together the flour, baking powder, ground mustard, salt, pepper, shredded cheese and half the crumbled bacon. Cut in butter until mixture resembles coarse crumbs.

Beat eggs in a small bowl with a fork, add eggs and onions along with sour cream. Mix well with a spoon until dough is wet and forms a ball in the bowl.

Place dough on a sprayed baking sheet and press with hands into a round circle about 1/2 inch thick. Sprinkle on remaining crumbled bacon and kind of press into dough.

Cut dough into 8 triangles. (I use a pizza cutter to cut the dough). Bake in preheated 400 degree oven for 20 to 25 minutes until browned on top.
