Preheat oven to 400 degrees F.
Coat a large baking sheet with cooking spray.
Arrange tortillas on prepared baking sheet and spray with cooking spray. Season the top of tortillas with cumin, salt and freshly ground black pepper. Bake 6 minutes, until golden brown and crisp. Remove from oven.
While the tortillas are baking, in a medium saucepan, combine cheese, artichoke hearts, salsa, and spinach. Set pan over medium heat and bring to a simmer, for 5 minutes or until cheese melts. Pour into a serving bowl.
In a large bowl, combine: the chopped avocados, lime juice, chopped cilantro, chopped tomatoes, salt and freshly ground black pepper and smoked paprika, to taste, if using.
Adjust seasonings, if necessary.
Serve cheese fondue with baked chips and guacamole.
