Crockpot Refried beans (cheap and yummy)

I've been tinkering around with this recipe and have got it perfect for our tastes! Hope no one minds If I share, it's super easy, healthy, and cheap- the perfect combo. Technically they aren't "refried" but they're still yummy.

• 3/4 onion (split into 2 pieces)
• 1 1/2 cups dried pinto beans (rinsed and soaked for 24 hours)
• 1/2 fresh jalapeno, seeded and chopped
• 3 tbsp. minced garlic
• a dash of salt
• a tsp.-ish amount of pepper
• 1 tsp. ground cumin (optional)
• 5 cups water

Put everything into your crockpot and cook on high for 8-10 hours (add more water if needed). Once the beans are cooked, strain them and reserve the liquid. Mash the beans with a potato masher, adding the reserved water as needed to attain your desired consistency. I like to sprinkle a little bit of cheese over the top. Did I say yumm yet?
