Thoroughly mix the Roasted Garlic/Shallot Sauce with the beef and set aside to marinate.
While the beef marinates, chop the vegetables
Melt the oil and butter in a sauté pan and begin to caramelize the onions over medium heat -- with s/p -- stir occasionally to ensure that they do not burn
Bring a pot of water to boil, add salt, and blanch the broccoli and carrots to set the bright color and par cook, take out and shock in ice water to stop the cooking.
Continue to stir the onions until they reach the caramel stage and then add the balsamic vinegar to the pot and finish cooking on low heat.
Next -- shape the burgers into oval 'steaks' and sear in a hot sauté pan on both sides and then put into the hot oven to finish cooking for 10 minutes.
Remove the steaks from the oven and allow to cool a bit.
Remove the steaks from the pan and set aside while making the gravy. Add shallots to the pan along with the white wine and allow to reduce. Add the consommé, mustard, ketchup, worcestershire sauce, s/p and continue cooking. Taste and adjust the seasonings, then puree in a high powered blender on high to create a silky gravy.
Serve the steak with the onion, vegetables and gray -- ENJOY!
