leftover lentil soup

I had planned on making dan's lentil soup tonight but then time passed, it's freezing outside and I was hungry - so here is my soup that is essentially "whatever I had in the pantry!"

Ingredients:

• 1 tbslp olive oil
• 1/2 onion, chopped
• 3 small stalks celery, chopped
• 1 large carrot, chopped
• salt and pepper
• 1 tsp cumin
• 2 c vegetable broth
• 14 oz can "bean, lentil and barely soup"
• 1/2 c cooked quinoa
• 1 c water
• 12 oz frozen sweet potato cubes

Instructions:

1. Make a mirepoix with the first 4 ingredients and add the salt, pepper and cumin.
2. Add the broth, soup and quinoa. Cover and let cook on medium for about 10 minutes.
3. Add water and sweet potato cubes and let cook another 10 minutes.
