Ooey Gooey Toasted Cheese

• Butter
• Really good crusty bread (I used rosemary sourdough)
• 1 1/2 cups very sharp cheddar, shredded
• 1 tablespoon mustard (Dijon or Colman's)
• 1 teaspoon Worcestershire sauce (optional)
• 1 teaspoon mayonnaise
• 1 pinch thyme
• 1 teaspoon finely minced onion
• 1 egg yolk
• Black pepper, to taste

1. Preheat the broiler. Butter one side of two large (or four small) thick slices of bread and toast under the broiler until brown. Flip them over onto a cookie sheet.
2. Mix the remaining ingredients and spread them onto the bread. Return them to the oven and cook for a couple more minutes until puffed, browned, and bubbly. Grind fresh pepper on top.
3. I served this with a simple butter lettuce and chive salad with balsamic vinaigrette (aged balsamic, Dijon, olive oil, salt, and pepper). The sweet vinegar and mustard are a great match.
