This was using just 8oz of dried pinto beans, along with some diced veggies.
Method and Ingredients:

Pre-soak beans overnight (in fridge). I usually add 1 tsp of kosher salt and 1/2 tsp baking soda.
Drain & rinse beans. Add to pot and cover with a finger or two of cold water.
In slow cooker (3 hours on high or 4 hours on low). on stove top, 90 mins on slight simmer.

Once the beans are softening, but not yet fully soft, add the following
1/2 Yellow Onion – diced
1/2 Green Bell Pepper – diced
1x Roma Tomato – diced
1x can Crushed Tomatoes
Additional water to cover.

Let cook another 30 mins
remove from heat and allow to cool for 1-2 hours
Portion into airtight containers (I used mason jars).

It should last around 5-6 days in the fridge, can be eaten hot or cold, with pasta, rice, potatoes, meats etc.

fwiw, I vac sealed these mason jars, which should extend fridge life to at least 10 days.
