Pat chicken breasts dry; dice into small pieces.
Heat oil in large pot (I use my dutch oven for this).
Add chicken, half of the spices and the lime juice and zest; sautee until chicken is cooked through.
Add beans, corn, red onion, scallions and the rest of the spices. Stir until combined with the chicken and heated through.
Taste for spices now - check for salt, pepper, cumin and chili powder. You could add more lime zest if you want a strong lime flavor!
Remove from heat.
Preheat oven to 350. Line a baking sheet with foil and spray with cooking spray. Set aside.
Wet a paper towel so it's damp, put a large dish on the side for you to place your prepared won tons. Place a small bowl of water to seal the won tons. Get ready to assemble!
Take one won ton and 2 tsp of the mixture. Place in the middle of the won ton. Dip your finger in the bowl of water, and run your finger around the inside sides of the won ton (the side you are looking at). Fold in half to make a triangle shape. Gently press the wet sides together until they stick.
Place won ton on dish, cover with damp paper towel. Continue with the remaining mixture and won ton wrappers.
Place won tons on the prepared baking sheet, about an inch apart.
Spray with cooking spray on the sides of the won tons facing you (on the baking sheet); bake for 25 minutes until the wrappers are crispy.
Serve with ranch dressing, cilantro, scallions and lime wedges.
