The night before you want to cook the beans (or at least 8 hours prior) you’ll want to soak your beans. Place beans in a large pot and fill with 8 cups of water. Place a lid on top and let sit for at least 8 hours if not 12 hours. After the beans have soaked, drain all water, rinse the beans, and set to the side.
Using a Multi-Cooker, preheat to sear setting. Place the bacon in the multi-cooker and cook for 2 minutes, stirring occasionally. Then add in the white onion, cook 1 minute, followed by the garlic and jalapeño. Mix occasionally and cook for a total of 10 minutes until the bacon starts to crisp and onions start to turn translucent.
Reduce the heat on the Multi-Cooker to “slow cooker high” mode. Add in the can of fire-roasted tomatoes and the beans. Mix well, then add in the salt and 6 cups of water. Mix well, place the lid on the beans and cook on high for 8 hours.
Once the beans are done place two cups of beans in a blender and puree. Drain excess water from the slow cooker. Pour the pureed beans back into the slow cooker, and mix in the freshly chopped cilantro. Serve immediately or keep on "warm" setting until ready to serve.
Don't have a Multicooker? Use a pan to in those steps when you need to sear, then transfer to a slow cooker!
