We used a casserole dish that ended up being perfect because it was the exact size of the tortillas. Here's how the layers went, from bottom to top:
Start with a bottom tortilla (after greasing the pan)
black beans with some shredded cheese (we used follow your heart which my very omnivore mother even said was decent enough)
rice cooked with a little bit of lime juice and cilantro (gives it a delicious smell)
black beans and refried beans mixed together
technically, you should just have each layer be a separate ingredient, but it was getting to tall.
we baked it at 350 degrees for 20 minutes (which was a complete guess) and then let it broil for a couple minutes to melt the cheese on top. (I actually broiled it too long because I was playing with my kitty and forgot to pay attention, but it was still good, just a little crispy.)
We topped it with tofutti sour cream and some salsa and had some fresh snap peas on the side, and it was uber-yummy! I've never had much faith in vegan cheese, but my mom saw it at the store and decided to give it a try. You couldn't really taste the cheese, but just got a little hint of it.
And if I knew how to put pictures on, I would post one! It actually turned out kinda pretty!
