Set the Instant Pot to "Saute", add the oil, and cook the pork until just beginning to brown. Add the onions and cook until softened. Add the garlic and cook for another minute. Add the beans, rice, diced tomatoes, broth, and seasonings and stir to combine.Cancel the "Saute" setting and set the Instant Pot to pressure cook on HIGH for 10 minutes followed by a quick release. Stir in the lime juice and chopped cilantro. Serve immediately. A tossed salad, cornbread, coleslaw, freezer slaw, collard greens, or corn on the cob make great accompaniments.
