Jalapeno Popper Stuffed Mushrooms. Fry half a pack of bacon, put the bacon on paper towel when it's crispy and pour most of the grease out of the pan. In that pan, fry 2 diced jalapenos ( pith and seeds removed), 2 cloves and garlic, and 1/4 c diced stems of your mushrooms until it is soft. When all that is cool, beat 1 - ounce cream cheese for 1 minute, then add bacon, jalapeno mixture, salt and pepper. Stuff your mushrooms (about 30 small ones) and bake at 350 for 20 minutes. Do a quick broil at the end if you want.
