Prep your crock pot by adding cooking spray to the bottom of the pot. Now layer your lasagna into your crock pot. There will be 3 layers of every ingredient (4 for tortillas and cheese). You'll need to divide up your ingredients evenly for the layers.
Here's how I layered it all in:
tortillas - 1 and 1/2 tortillas fit in the bottom of my crock pot
refried beans - 1/3 of 2 cans
ground beef - 1/3 of the beef
salsa - 1/3 of the jar
shredded cheese - 1/4 of the bag
REPEAT 2 more times - for 3 layers
top with tortillas and cheese
TIP: for the refried beans, I used a cake decorating spatula to spread it evenly on each layer and it worked great!
With all your ingredients layered up, and it's ready to bake. Set your crock pot on High for 4-5 hours or Low for 6-7 hours.
Once the lasagna is done, let it sit in the crock pot for another 30-45 minutes to let it set before you cut and serve. Top it with sour cream, maybe some fresh tomatoes and guacamole, and add your fun little toothpick football signs. It's ready for game day!
