Okay, here's a recipe that I haven't actually tried yet, but it sounds good. I watched it prepared on a "Healthy Decadence" episode on discovery health, then I found pretty much the same recipe in the newspaper food column. You can use this recipe for fish sticks, fish, chicken or pork filets as well:

Baked Popcorn Chicken (or chicken fingers, fish sticks, filets, etc.)

Olive oil cooking spray
2 large egg whites
2 T Dijon mustard
1/2 t salt
2 c panko (Japanese-style) bread crumbs
1 1/2 pounds boneless, skinless chicken breast cut into 1-inch cubes

Heat the oven to 450 degrees. Coat a large baking sheet with cooking spray. In a medium bowl, whisk together the egg whites, mustard and salt. In a shallow bowl or pie plate, spred the panko. Add the chicken pieces to the egg white mixture and toss to coat. A few pieces at a time, transfer the chicken to the bread crumbs and toss to thoroughly coat. Transfer the breaded chicken pieces to the prepared baking sheet, arranging them close together but not touching. when all of the chicken is on the baking sheet, spritz them lightly with cooking spray. Bake for 15 minutes, then use a spatula or tongs to flip the chicken pieces. Continue baking until golden brown and no longer pink at the center, another 5-10 minutes.
