Peel and finely chop the onion and mince garlic.
Heat a skillet over medium heat, drizzle with olive oil, add the onion, and season with a pinch of salt.
Sauté for about 3 minutes until softened, add the garlic, and stir for an additional 1 minute or until fragrant.
Add 2 ladles of the cooked beans to your skillet, mix, and mash the beans with the spatula - this puree helps thicken your beans. Add you sazon or sazon replacement seasonings.
Transfer the sautéed mixture with mashed beans to the pot with the cooked beans.
Season with salt and pepper to taste, mix, and let it cook, uncovered, for another 10 minutes or until the broth thickens - the time may vary depending on the desired consistency, whether thinner or creamier. (If using and instant pot you can use the saute function for this)
Add parsley and green onions if using
Stir occasionally to prevent sticking to the bottom of the pot.
Remove bay leaf
Turn off the heat and serve.
