Sweet port softens the bitter edge of this endive appetizer that is sure to please.
Heat oil in a large skillet over medium-high heat. Add endive, cut-side down, and cook until very brown, about 3 minutes. Flip and add port. Reduce heat to maintain a simmer, partially cover and cook until the port is mostly evaporated, 5 to 7 minutes.
Meanwhile, heat butter in a small skillet over medium heat. Add breadcrumbs and cook, stirring occasionally, until crispy, about 2 minutes. Remove from heat.
Season the endive with salt and pepper. Serve topped with the breadcrumbs and dill.
