Easy Vegan Frito Casserole

This one is a throwback (and how can it not be, with a name like Frito casserole). My mom used to make this for us when we were little, only with ground beef. I tweaked the recipe just a bit to make it vegan. I know this sounds silly, but seriously, it's so good!
Ingredients
1 can chili beans
1 can black beans (rinsed & drained)
1 can tomato sauce
1/2 cup chopped red onion
1 chopped pepper (red, yellow, or orange)
1/3 cup almond milk
1 tbsp flour
1 tbsp chili powder
1/4 tsp black pepper
1 tsp cilantro (optional)
Fritos (lightly salted, if you can find them!)
Optional toppings
avocado
jalapenos
cheese
sour Cream
Now all you need to do is combine all the ingredients in a big bowl until mixed...

And then transfer to your 1.5 quart round casserole dish...

Top with however many Fritos you feel like topping with, and cook for 30 minutes in a 350 degree oven.

After patiently waiting half an hour, add a few toppings and enjoy!
Note: The dish on the left does have dairy cheese on it - but mine on the right is sans dairy! One thing I want to try making this year is vegan cheese...intimidating!

What are some of your so-easy-you-can't-believe-it's-vegan favorites?
