Cheesy Tortilla Soup Recipe

So I'm totally not a soup person, but I was flipping through my tasteofhome cook book, 'Mom's Best Made Easy'. And found this recipe and thought, this could be awesome. So what do you know, I went to the store, purchased all the ingredient's, and it was the BEST soup I've ever had. Caleb absolutely loved it too. It also made enough to store two huge containers in the freezer for a rainy day!

1 package of Taco Seasoning
1 pound of boneless chicken breasts, diced
2 tablespoons vegetable oil
1/2 cup chopped onion
1/4 butter, cubed
1/3 cup all-purpose flour

1 cup cubed Velveeta
1 1/2 cups of shredded Monterrey jack cheese
