Also try using different types and boldness variations of Cheddar, or sub Monterrey Jack or a mixture thereof. Those shredded Mexican/Taco cheese packages work well too. I use lots of jalapenos!!! Sometimes I add cayenne as well. If you want a milder version, remove the seeds of the jalapenos before you cut them. But try to use as much peppers as you can stand as it really gives it more dimension. Check your local gourmet market for milder peppers as well if you are sensitive to the heat.
