Breakfast sandwich

Slice the onion, fry it in the oil. Scoop in a slotted spoon and set aside once golden on a paper towel.

Mold the sausage meat into two bagel-shaped forms. Pan fry in the onion oil.

Toast the bagels lightly

Add mustard and spinach to one half of the bagel, and mustard and onions to the other half. Top both with a thin layer of cheese. Broil until cheese is melted.

Add sausage ring, squish sandwich together, and enjoy!
