"Not that pleasant to look at, but who is during camping? This recipe is good for the last night of camping because you can basically throw in all the leftover meat along with the roast beef, and it still tastes great!"
Melt butter and oil in a large frying pan over the hot coals of a campfire. Stir in potatoes and onion, and cook until the onions are translucent. Add the linguica and continue cooking until the linguica has browned. Stir in the roast beef, and cook until warmed. Add the corn with it's juice, and allow to simmer for 10 minutes.
