Heat olive oil in a large skillet. Add green pepper, celery, onion, and garlic, and saute until tender.
Add vegetable stock, tomatoes, tomato sauce, and the spices to the skillet. Bring to a boil.
Once boiling, add rice and reduce heat to low. Cover the skillet and let ingredients simmer (for about 20-25 minutes) until the rice is tender and a great deal of the juices have been absorbed.
Stir in beans and let cook for about five more minutes.
Remove from heat and let cool a little before transferring to a freezer dish.
Spray freezer dish with a non-stick spray (I use olive oil). Transfer jambalaya to the freezer dish. Cover with plastic wrap and then dish cover. Place in refrigerator to cool completely. Once cold, transfer to freezer.
To prepare for serving: thaw in refrigerator, then warm in the oven (at 350°F). You could also warm on the stove top by transferring ingredients to a skillet. Last but not least, warm individual servings in the microwave.
