This is a firehouse favorite invented by my son, Ian, a firefighter with the Southern Marin Fire Department. You can make the sandwich mild or five-alarm hot, depending on what type of sausage you prefer.
| 1 | tablespoon | olive oil |
| 1 | tablespoon | butter |
| 1/2 | medium | red onion, sliced |
| 1 | sausage | |
| 1 | hard French or sour dough roll, split | |
| ~ | honey mustard | |
| ~ | coleslaw, drained | |
| ~ | salt | |
| ~ | freshly ground black pepper |
- Place the olive oil and butter in a heavy-bottomed skillet set over medium-high and heat until it sizzles.
- Add the sliced onions, lower the heat a bit, and cook, stirring occasionally, until golden brown and translucent -- approximately 8 to 10 minutes.
- Turn off the heat and keep the onions warm in the skillet while you prepare the other ingredients.
- Split the sausage and grill or fry it for about two minutes on each side.
- Cut the roll in half lengthwise and grill or warm it.
- Slather with the honey mustard.
- Place the onions on the bottom roll and top with the sausage.
- Sprinkle with the salt and pepper and top with approximately ¼ cup of drained coleslaw.
- Top with the second half of the roll, gently press down, and serve immediately.
