For any of you that are beef lovers, this is an amazing recipe for beef steak! Just make certain to tell your butcher to cut the sirloin to 2-1/2 inch thickness for this recipe. This steak is broiled then baked in the oven in a savory sauce, served topped with delicious mustard sauce, If desired you can just omit the mustard sauce, the steak is really wonderful without it also! The mustard sauce can be prepared hours in advance and refrigerated, then warmed in the microwave when ready to use. This recipe serves two people easily, but can be doubled if desired, just double all ingredients and prepare the with the same method...This is wonderful served with baked potatoes...you will love this!
