Grilling peppers and onions

Grill the vegetables in a grill basket. The basket helps to prevent the vegetables from falling through the grates. You can also make a homemade basket out of tin foil.

If you’re looking to save time, prep the vegetables in advance by slicing and combining with the olive oil, salt and pepper. Cover and store in the refrigerator for up to 2 days. When you’re ready to eat, remove them from the refrigerator, grill and enjoy!

Homemade grill basket with foil

To make a grill basket with tin foil, take one large piece of tin foil. Fold it in half and then fold up 1-inch on all sides to make the edges. Use a fork to poke holes in the bottom of the tin foil to create vents. Place the vegetables on the tin foil and place directly on the grill grates.
