Not so healthy, but ... Easy Sweet and Sour Crockpot Seitan (vegan)

photo from here.
(I ate it up before I remembered to take a pic! It looked just like this though!)

Ingredients:
1 lb seitan, cut into chunks (I bought two 8oz packages)
6 carrots, peeled and sliced into rounds
1 large onion, chopped
1/3 cup brown sugar
3 tablespoons soy sauce
3-4 large garlic cloves, minced
1-2 teaspoons red pepper flakes (I like it spicy; decrease amount if you don't.)
1 (20oz) can pineapple chunks, drained and juice reserved
3 tablespoons cornstarch
3 tablespoons cold water
1 red bell pepper, seeded and chopped
1 green bell pepper, seeded and chopped

How to:
1. Place seitan, carrots, and onion in crockpot.
2. In a small bowl, mix together the brown sugar, soy sauce, garlic, red pepper flakes, and pineapple juice until sugar is dissolved. Pour into crockpot.
3. Cook on low 8 hours.
4. 30 minutes before serving, dissolve the cornstarch in the water and add the mixture to the crockpot along with the bell peppers and pineapple chunks.
5. Turn crockpot up to high and cook for 30 minutes, until peppers are crisp-tender.
6. Serve over rice or couscous. Enjoy!
