1. Cook and drain macaroni as directed on package.
2. In 10-inch skillet, melt butter over medium heat. Using whisk, stir in flour, ½ teaspoon salt and onion. Cook 2 to 3 minutes, or until mixture smells nutty and is lightly golden, stirring constantly with whisk.
3. Add milk. Continue to beat with whisk, scraping bottom of skillet until mixture heats to boiling. Mixture will thicken. Remove from heat; add cheese and dill. Stir with whisk until smooth. Stir in drained macaroni.
4. In a medium bowl, mix ground beef, 1 teaspoon salt, and 1/2 teaspoon black pepper. Form into 4 patties.
5. Cook the burgers in a medium skillet for 6-8 minutes per side, or until the internal temperature reaches 165°F, and burgers are browned all the way through.
6. Place a piece of lettuce on the bottom section of one of the buns and add one burger patty. Scoop a generous portion of the mac and cheese onto the burger. Top the burger with mayo and place the top of the bun on the burger.
