Method

Bake the baguettes according to pack instructions.
Put the sliced red onions in some ice water for 10 mins to get rid of some of the bite.
Mix together ingredients for garlic butter, then microwave for 30 secs. Slice the baguettes in half, then brush inside and out with the garlic butter.
Preheat the grill to high.
To make the salad, combine the mayo, garlic powder, Italian seasoning, red wine vinegar, chives and jalapeños in a large bowl, then stir in the red onions and lettuce and mix well. Season with salt and pepper to taste.
Layer each side of the bread with the Cheddar cheese and place under the grill for a few minutes until melted.
Remove from the grill and layer with the sliced tomatoes and leftover beef. Season well, then top with the grinder salad and Parmesan, then close the sandwich and enjoy!
