The BEST Chicken Tortilla Soup -thanks Melinda

I have been craving this soup but it seems weird to make soup when its 90+ degrees outside.

Chicken Tortilla Soup

1 medium onion
1 14 oz can diced tomatoes
6 cups chicken broth
4 Tbsp lime juice
½ tsp dried oregano
¼ tsp sugar
Tortilla chips
Shredded cheddar cheese
Fry chicken in pan with garlic, shred and set aside. Dice onions and saute in oil. Add everything together in a large pot. Bring to a boil, then cover and let simmer on low 1 hour.
Crumble chips in bowl add soup and then put cheese on top.
