Combine chicken and taco seasoning mix in a heavy duty zip-top bag; toss to coat. Refrigerate for 1 - 2 hours or overnight.
Place chicken in a broiler pan or in a 15 x 10 x 11 inch jellyroll pan.
Broil coated chicken 6 inches from heat (with electric oven door partially open) for 5 - 6 minutes. Remove from oven and cool.
Cut chicken into bite-size pieces.
In a bowl, combine chicken, cheese, picante sauce, and red peppers; stirring well. Set aside.
Brush 1 side of each tortilla with melted butter; place 2 tortillas, buttered side down, on a cookie sheet. Top each tortilla with about 1 cup of chicken mixture, spreading to edges of tortilla. Top each with a tortilla, buttered side up.
Bake at 375 degrees Fahrenheit for 10 minutes or until golden brown. Cut into wedges. Repeat with remaining tortillas and chicken mixture. Serve immediately.
NOTE: If making these into burritos, mound chicken mixture 1/4 of the was down on tortilla's. Turn over short side of tortilla over chicken. Turn both right and left sides of tortilla about 1 inch inches Roll up cigar style, enveloping the chicken mixture tightly. Place on greased cookie sheet, seam-side down. Brush each burrito with melted butter. Bake until golden brown.
Note # 2:If you can find Chi-Chi's taco seasoning mix, these will be To Die For. But unfortunately I can't find this seasoning anymore. They used to advertise right on the package that it didn't contain the "red stuff". I use other taco seasoning mixes, but none compare to the goodness that Chi-Chi's had. If you can find Chi-Chi's somewhere, use 2 pkg's because each pkg. was about 1 /2 - 3/4 ounces. If you do find it, let me know, because I'd love to know because I've been searching for a long time.
