Cheesy Chicken Rotini

For some reason my picture didn't come out very well.  The colors on this dish are actually quite pretty and vibrant.  Oh, well...  the dish is so simple and delicious!  The flavors blend beautifully and I love that there's no seasoning in the dish.  The cheese combined with the tomatoes and the little kick from the chilies do the trick for an amazing flavor.  Enjoy!
-2 large chicken breasts, boneless, skinless, cut into 1 inch pieces
-2 cups water
-3 cups garden rotini, uncooked
-1 (16 oz) package frozen broccoli and cauliflower mix
-1 (10 oz) can mild diced tomatoes with green chilies, undrained
-1/2 lb Velveeta cheese, cut into 1/2 inch cubes
Coat large skillet with cooking spray.  Add chicken and cook until no longer pink.  Add the water and the pasta.  Cover and cook for 10 minutes, or until pasta is cooked through.  Add the rest of the ingredients.  Cover and cook until cheese is completely melted, stirring occasionally.  Enjoy!
