Great!

I omitted the anise seed because I didn't have it and I added four cloves of fresh minced garlic to the butter before brushing it on the thick hamburger rolls, which we used instead of baguettes. I made six thick burgers instead of twelve thin. These are incredible. We really loved them. We dressed these simply with homemade special sauce, sliced cheddar cheese, sliced tomato, sliced onion and fresh bibb lettuce. Out of six, there is ONE left. My husband ate two in one sitting. I'll make these again for sure.

Instead of sandwiches, I used this hamburger as part of a "naked burger" (no bun) meal idea to serve 4 (changed the serving size). Made a few tweaks w/ingredients I had on hand: used ground turkey instead of ground beef, hot Italian sausage, 3/4 of an onion, 4 garlic cloves and increased the Italian seasoning. These were a hit with my husband, he's already requested I make them again! Very easy to prepare and add/sub out ingredients you have in your fridge.

Successful meal. Three of us thought they were really tasty but my daughter thought there was too much flavor of Italian sausage - probably from the 2 teaspoons of fennel seeds. I actually used two pounds of lean ground beef and one pound of bulk sausage and used the full recipe amount of seasonings. It was too hot to grill outside so I grilled them on my stovetop pan and then finished in the oven. After putting the cooked meat patties on sub rolls, I added sauteed red peppers and onions and provolone cheese, wrapped in foil and heated for 15 minutes. My daughter added pesto to hers after it came out of the oven. I don't think serving them on the bun is necessary. They would be good covered in grilled veggies and shredded cheese and heated in the oven until the cheese melted.
