Spicy Beef and Onion Sandwiches

  I still remember my brother Eldon telling my Mom that she had made the best beef sandwich ever and that he would never forget it, fast forward a few years and with that image still in my mind I set out to make the BEST beef sandwich ever, so with cookbook in hand and determination in heart, I fried and cooked and plated until I heard the words I so longed to hear " Hey Sis, these are the best beef sandwiches ever" and with my beef sandwich cooking destiny fulfilled, I feel free to share the  recipe with you.

Spicy Beef and Onion Sandwiches

6 ounces beef top sirloin steak, cut 1 inch thick
1 medium onion, thinly sliced
1 tbsp mustard seeds
1/2 cup water
1 cup sliced mushrooms
1 tbsp sugar
1 tbsp cider vinegar
1 tsp olive oil
3 kaiser rolls
3 tbsp spicy brown mustard

Start off by melting a tablespoon of butter or margarine in a skillet over medium heat until the pan is hot. Add your beef and partly cover your pan and cook 4 minutes on each side or until completely cooked, then remove the beef from the pan. Add the onions, water, and mustard seeds to the pan and cook on medium high heat, or until all the water has evaporated. Add your mushrooms, vinegar, sugar, and olive oil. Cook five minutes or until the onions have browned.Cut your rolls in half and spread the mustard onto them. Slice your meat thinly and place onto the sandwiches and top with the onion mixture. Serve and enjoy!
