Press the SAUTE setting on your Instant Pot and spray with avocado or olive oil. When hot, add onion and saute for a few minutes. Add the smoked paprika and garlic powder, cook for 1 minute, or until fragrant, stirring frequently.
Next add the beans, broth, tomato paste, maple syrup, lemon or lime juice, mustard, ground pepper and salt, gently stir until the tomato paste is dissolved completely and everything is well combined.
Attach the lid, and make sure the vent is in the SEALED position. Push the PRESSURE COOKER button, and manually set at HIGH for 75 minutes. When done, let the steam vent on its own, takes about 20 minutes. Move the vent to open, careful not to burn yourself as there may still be a little steam left. Remove lid and let cool a bit, add salt to taste. Transfer beans to a serving dish.
Beans will thicken once cooled. If too thick, add 2 tablespoons of water at a time, mix well, and repeat until desired consistency.
