This diner classic gets a makeover by replacing some of the ground beef with finely chopped portobello mushrooms, which add moisture and flavor. We like a smear of pickle relish on top, but you could try chutney, mustard or hot pepper relish in its place. Make it a Meal: Round out the plate with Oven Sweet Potato Fries and Balsamic & Parmesan Roasted Cauliflower.

Makes 4 servings

ACTIVE TIME: 30 minutes

TOTAL TIME: 30 minutes

EASE OF PREPARATION: Easy

12 ounces 93%-lean ground beef
2 cups finely chopped portobello mushroom caps (about 2), gills removed
3 tablespoons plain dry breadcrumbs
1 tablespoon Worcestershire sauce
1 teaspoon chopped fresh thyme or 1/2 teaspoon dried
1/4 teaspoon salt
1/4 teaspoon freshly ground pepper
4 slices rye bread
1 clove garlic, peeled
8 teaspoons pickle relish
4 slices Swiss cheese (2 ounces)

1. Position rack in upper third of oven; preheat broiler. Line a broiler pan with foil.
2. Gently mix beef, mushrooms, breadcrumbs, Worcestershire, thyme, salt and pepper in a medium bowl until combined. Shape into 4 patties and place on the prepared pan. Broil until cooked though, 4 to 6 minutes per side.
3. Meanwhile, toast bread. Rub each slice of toast with garlic.
4. Place 1 patty on each piece of toast, top each with 2 teaspoons relish and cover with a slice of cheese. Remove foil and place the sandwiches on the pan; broil until the cheese is just melted, 30 to 60 seconds.

I just made these last night for the first time - they were awesome! My husband asked if we could have them at least once a week. The sweet relish added a great contrast to the beef and mushrooms.

Loved these. I put these on whole grain toast to up the fiber. I did them in a nonstick skillet.

These were fantastic. My boyfriend and I loved them and loved that they were lower fat. The portobello really does keep them fantastically moist.

These were terrific. My boyfriend raved about them.

I made this and adjusted to fit with my Weight Watchers diet... very good... I used the 100 cal. English muffins and Laughing Cow Light...

This was the best hamburger I have ever had! They were very moist and flavorful. I grilled them and put them on toasted buns. Delicious! (I did not add the pickles, however.)
