In a large pot, melt butter over medium-high. Add cauliflower and cook, stirring occasionally, until it begins to brown, 4 minutes. Addgarlic and cook until fragrant, 1 minute. Add orange juice and honey; season with salt and pepper and cook until liquid is reduced and syrupy, 3 minutes. Add broccoli rabe and cook, stirring occasionally, until crisp-tender, 3 minutes.
