I made this a late night movie snack between movies we were watching - it took less than 10 minutes. It is great if you want a quick warm snack on a cold night.
Cut the cheese product in half - put one half away as you will only need 1 lb, unless you want it to be extra cheesy.
Cut up the half of the cheese you are going to use and melt it on low heat, stirring constantly for a few minutes.
Once the cheese is melted, open the can a tomatoes add them to the cheese and stir. If you choose to add any optional items, stir them in at this point also.
Remove from heat, pour into serving bowl and serve with tortilla chips.
