In a large pot cook chicken. (I like to spray the bottom of the pot with a little bit of cooking spray) Remove Chicken and chop into cubes (you could shred if you would like but I like it chunky) Place back in the pot. Add purple onion, peppers, cilantro and garlic. Cook until all is softened. Add water, stock, beans and corn. Add salt and pepper to taste. Add salsa. (I use HOT- but if you like mild or medium then use that) Slice tortillas in strips and place on a baking sheet. Place in 350 degree oven for about 10-15 minutes checking and flipping regularly as you are only drying these out not baking. (Corn may take longer). Garnish each bowl with avocados, green onions, cilantro, sour cream, and tortillas. Enjoy!
