1 pound beef mince
1 onion, chopped
oil
3 tablespoons flour

Add oil to hot deep skillet along with the beef. As the meat begins to brown, add onions, salt, and pepper. Reduce heat to a simmer and cook thoroughly. Stir flour into beef and onion mixture until totally absorbed.

Slowly add milk, stirring constantly, until thickened. Taste and adjust salt and pepper.
