I've tried a handful of recipes from Pinterest in the last while, some have been epic fails and others a success. Here is one that I would label a success! Balsamic and Onion Pot Roast
There is a fair amount of prep work required before placing it all in the crock pot. If you plan to start it in the morning before leaving for work you will want to allow yourself a little extra time. The only change I made was to cut the amount of vinegar to 1/4 cup. There were more onions than roast left after we finished dinner. I saved the onions and placed them on top of grilled burgers the next day. Delicious!
