I saw a recipe recently in a Family Circle magazine (I think) for French Dips. I adapted it to make a quicker version, using deli-sliced roast beef. We have a grocery store nearby that sells nitrate-free deli roast beef. Here's my easy version. I hope you try it!
1 cup lager beer
1 can low sodium beef broth
1 T. soy sauce ( this adds a good flavor)
1 lb. thinly sliced deli roast beef
In a non-stick skillet, melt butter & add onion. Cook, stirring occasionally for 5-10 minutes.
Add the beer, broth. soy sauce & pepper. Bring to a simmer & cook 3-5 minutes.
