Preheat the air fryer to 375 F. Add the tofu in a single layer and cook for 8 minutes. Flip and cook another 6 minutes until brown and crispy.
While the rice and tofu cook, make the dressing. Add the white parts of the scallions, lemongrass, ginger, lime juice, soy sauce, sriracha, and dates to a blender or food processor. Blend until smooth. If the dressing is too thick, add more lime juice or water.
Steam the broccoli in a basket steamer on the stove. Add water to a wide pot just shy of the bottom of your steamer basket. Bring the water to a boil, then add the broccoli florets and diced stems. Cover the pot and steam the broccoli for 2-3 minutes or until the broccoli is green and tender. Promptly remove the pot from the burner and the lid to stop cooking.
Combine the rice, broccoli, green parts of the scallions, tofu, and cilantro. Add the dressing and mix to combine. Fold in a few chopped peanuts or save them for the top of the salad.
