Step 1

Prepare onion and pepper mixture at home. Saute with 2 Tbsp butter and 1/4 cup oyster sauce. Pack in a container to take camping.

Step 2

Start by cutting slices into the bread about 1.5 inches apart and not all the way through to the bottom. Butter the insides of each slice.

Step 3

Drop a large scoop of the pepper mixture into each cut.

Step 4

Stuff with roast beef and cheese.

Step 5

Wrap in foil and place near the campfire coals to heat through until melty and golden.

Step 6

Slice the loaf into "sandwich" servings, cutting the bread all the way through, between your 1.5 inch slices from earlier.
