Quick crock pot question

[klpmommy]

If I am making soup and I want to put tortillas in it to make it a tortilla soup, at what point do I put the tortillas in? I'm adjusting a regular soup recipe to make it crock pot, so my directions aren't helping.

soft tortillas? I'd probably add them in the last 1/2 hour or so.

I googled tortilla soup and slow cooker to see what the general consensus was as I've never made that specific meal. This seems to be what others do:

In CROCK-POT Slow Cooker, combine shredded chicken, whole tomatoes, enchilada sauce, onion, green chilies and garlic. Add water, chicken broth, cumin, chili powder, salt, black pepper and bay leaf. Stir in corn and cilantro. Cover and cook on LOW 6 to 8 hours or on HIGH 3 to 4 hours.

Preheat oven to 400F. Lightly brush both sides or tortilla with vegetable oil.

Cut tortillas into 2 1/2 x 1/2-inch strips. Spread tortilla strips onto baking sheet. Bake, turning occasionally, until crisp, 5 to 10 minutes. Sprinkle tortilla strips and grated Parmesan cheese over soup. Serve immediately.
