Grilled Sirloin Tri-Tip

1 . Stage

Combine balsamic vinaigrette, Worcestershire sauce, Dijon mustard, lime juice, and pepper in a gallon-size resealable plastic bag. Press out most of the air, seal the bag, and gently squeeze the ingredients to mix together.

2 . Stage

When marinade is well mixed, add tri-tip, making sure all sides are coated with the marinade. Squeeze out as much air as possible, seal the bag, and allow to marinate in the refrigerator for at least 8 hours, turning occasionally.

3 . Stage

Preheat an outdoor gas grill to 400 degrees F (200 degrees C), according to manufacturer's recommendations, making sure grill grates are clean. Saturate a paper towel with cooking oil, and use tongs to rub oil on the grate.

4 . Stage

Place tri-tip on oiled grate, close the lid, and grill for 3 minutes. Using tongs or a meat fork, rotate meat a quarter-turn, close the lid, and grill for another 3 minutes. Flip the meat and repeat.

5 . Stage

Leaving one burner on, turn off the burner on one side of the grill and move the tri-tip to the unheated side. Close the lid and continue cooking for 5 or 6 minutes, depending on the thickness of the meat.

6 . Stage

Test the interior temperature with an instant-read thermometer, inserted into the thickest part of the meat. Continue cooking until the meat reaches the desired degree of doneness, see note on the bottom.

7 . Stage

Remove the meat from the grill to a cutting board and tent with foil. Allow to rest for about 10 minutes. This is an important step in the process because residual heat will allow the meat to continue cooking.

8 . Stage

Cut into thin slices across the grain of the meat and serve.
