Campfire Roast Beef Stuffed Sandwich

More and more families are choosing camping as a way to vacation. Camping shelters run the gamut from simple tents to truck-hauled trailers to giant recreational vehicles. No matter how you choose to camp, here's a recipe that will impress even the most seasoned camper.

This hearty Roast Beef Stuffed Sandwich is a nice alternative to traditional foil pack dinners and will feed several. You can prepare much of the ingredients ahead of time before you leave for your adventure. Then it's just a matter of slicing the bread, assembling and heating it through when you're ready to eat.

We used a loaf of French bread which seemed to be a little too narrow. I think a wider loaf of Italian bread would work better. Be sure to pack a bread knife like Cutco's 7-3/4" Petite Slicer to slice slits into the bread vertically along the length of the loaf. The cavities are eventually stuffed with the delicious roast beef sandwich ingredients. You could also slice the loaf of bread it in half horizontally and layer the ingredients inside like a traditional sandwich.

Another handy tool to have on hand is the Spatula Spreader for generously spreading the garlic butter into each slice. It's the flavor boost that takes this stuffed roast beef sandwich over the top. 

Filled with onions, peppers, mushrooms, thinly sliced roast beef and Provolone cheese it will make an impression at the campfire. And, don't be stingy when packing the ingredients in. There's plenty to fill each cavity with a generous amount.

The sandwich can also easily be made at home on a gas grill set to low or in an oven, heated to 375 degrees F.
