I found this recipe after buying a london broil on sale and having no clue how to fix it. I will let you know how it is after I fix it.
(Found on allrecipes.com)
2 pounds london broil
1 (10.75 ounce) can condensed cream of mushroom soup
1 (10.75 ounce) can condensed tomato soup
1 (1 ounce) package dry onion soup mix
Cut the meat if necessary to fit in the bottom of the slow cooker. Combine condensed soups in a bowl and pour over the meat. Sprinkle the dry onion soup mix over the top. Cook on low 8 ~ 10 hours.
