Preparation
Step 1
Heat oil in large nonstick skillet over medium heat. Add onion; sauté 5 minutes. Reduce heat to medium-low; cover and cook until onion is very tender and golden, stirring frequently, about 25 minutes longer. Season with salt and pepper. Cool slightly.
Step 2
Butter 2 bread slices. Place bread, buttered side down, on platter. Divide onion, ham, cheese, and frisée between bread slices. Top each with another bread slice; butter top slices.
Step 3
Heat another large nonstick skillet over medium heat. Add sandwiches and cook until bread is golden brown and cheese melts, pressing occasionally with spatula, about 4 minutes per side. Cut sandwiches in half diagonally and serve immediately.
