Slow-cooked onions add moisture and flavor to these lean beef burgers for two.

We love the dill relish here, but use sweet relish if you prefer it.

Serve with sweet potato fries.

Classic Burger for Two

Combine 1 onion, 1 1/2 teaspoons oil and 1 1/2 teaspoons ketchup in a small saucepan.

Transfer to a medium bowl and let cool for a few minutes.

Form into 2 patties, each about 3/4 inch thick.

Oil the grill rack (see Frequently Asked Questions).

Assemble the burgers on 2 toasted buns with the ketchup-mayonnaise sauce.

Then, top each burger with an equal portion of 2 tomato slices and 2 lettuce leaves.

But be careful not to overcook it, or you’ll end up with a hockey puck.

The ground beef in this burger is an excellent source of protein, iron and vitamin B12.

The bun adds complex carbohydrates for energy.

If you want to up the fiber content, use a whole-grain bun.

The tomato, lettuce and onion add a little bit of fiber, vitamins and minerals.

Prepare ketchup-mayonnaise sauce (Step 3) and refrigerate for up to 1 day.

Oil a folded paper towel, hold it with tongs and rub it over the rack.

(Do not use cooking spray on a hot grill.)
