There's really no big secret to this recipe, it's just really easy and yummy and my family has been loving it lately. I just slow cook a roast all day in the crockpot and then purchase our favorite baguettes and put it all together. Since our family is still small we'll have roast etc. one day and a couple of days later have the sandwhiches with the leftovers.
In crockpot put
1 sliced onion
bag of baby carrots
a little salt
2 C beef broth
Slow cook all day.
The baguettes are from Classy Cuisine in Riverwoods. You buy them for $2 par-baked and stick them in the oven at 350 for 8 minutes and they come out crusty on the outside and soft on the inside.
Slice open the baguette, put in meat and serve with leftover sauce. You can also add cheese and carmalized onions.
