Farmers' Market Sliders

Preheat grill to medium-high.

To prepare mayo: Whisk mayonnaise, pickle, garlic, lemon juice and Cajun seasoning in a small bowl.

To prepare sliders: Combine beef, Worcestershire, salt and pepper in a medium bowl. Form into 6 patties, about 3 inches in diameter.

Oil the grill rack (see Tip). Grill the burgers until an instant-read thermometer inserted in the center registers 160 degrees F, 3 to 5 minutes per side. Grill zucchini, squash and onion until lightly browned and tender, 2 to 3 minutes per side.

Assemble each burger on a bun with a scant 1 tablespoon of the Cajun Mayo, the grilled vegetables, tomato and basil.
