Marinate chicken tenders in a southwestern or chipotle flavored marinade.

Preheat your grill to medium high heat, and slice the onion and peppers into long thin strips.

In a large zip top bag, toss sliced veggies with olive oil and garlic salt. Grill the vegetables in a perforated grill pan.

After the veggies have been cooking for about 10-15 minutes, place chicken on the grill. Reduce the grill heat to medium. Cook chicken tenders for approximately 6 minutes, turning once.

Lightly butter one side of each tortilla, and quickly heat the tortillas on the grill.

Slice the cooked chicken into long strips, and assemble veggies, chicken, and tortillas into fajitas, topping with either guacamole or sour cream and salsa, or all three if that makes you happy!
