I made this up to use leftover grilled steak. It's a delicious, hearty soup that is perfect with a salad and some homemade biscuits or beer bread on the side. Almost any kind of steak should work, although we usually grill New York, porterhouse, or sirloin. If you don't usually have leftover steak, you can always grill an extra one just so you can make this soup! You can adjust the heat by using a milder or hotter salsa, adding cayenne or chipotle, or adding jalepeno or other hot peppers.
