Cheesy Hamburger Dip

I needed to bring a dish to pass at a campground this weekend, so I decided to make up this dip ahead of time and reheat it to serve with chips for the pot luck.  I haven't made it for a while, but it smelled and tasted as awesome as I remembered.

Cheesy Hamburger Dip

1 LB hamburger
1/2 cup onion - chopped
1 clove garlic - minced
dash garlic salt
1 can tomato soup
1/4 cup ketchup
3/4 tsp oregano
1 tsp sugar
8 oz cream cheese
1/3 cup parmesan cheese
tortilla chips

Brown hamburger with onion and garlic, add garlic salt and simmer 5 minutes. Add soup, ketchup, oregano, and sugar. Simmer 10 minutes. Add cheeses and cook until bubbly. Place in a mini crockpot to keep hot. Serve with tortilla chips.
