Instructions
Mix garlic, soy sauce, Worcestershire, sugar, Dijon, paprika, and 1 tablespoon of olive oil in a medium bowl. Stir until the sugar dissolves.
Add steak cubes to the marinade, coat well, and cover. Refrigerate for at least 2 hours or overnight for more flavor.
If using wooden skewers, soak them in water for 30 minutes to avoid burning. While they soak, shave zucchini with a Y-peeler into ribbons (you’ll need about 48). Put the zucchini and tomatoes into a large bowl, toss with the remaining 1 tablespoon olive oil, and season with salt and pepper.
Alternate one steak cube, two folded zucchini ribbons, another steak cube, and a tomato. Repeat this pattern. You should end up with about 12 skewers.
Heat your grill to medium-high (around 400°F). Oil the grates using tongs and a paper towel dipped in oil.
Place skewers on the grill with space between each. Close the lid and cook for 3 minutes. Flip and grill another 3 minutes with the lid down. The steak should be seared and veggies slightly softened.
Remove skewers from the grill, rest for 3 minutes, then serve.
Notes
Chef Jenn's Tips
Sirloin stays juicy and cooks fast—great for skewers.
A Y-peeler makes shaving zucchini easier and faster.
Don’t crowd the grill so each skewer gets a good sear.
