Step-by-Step Instructions for Grilled Vegetables

Slice vegetables into uniform pieces to ensure even cooking. For example:

Zucchini: ¼ inch thick slices

Bell Peppers: Large flat strips
-
Mushrooms: Leave whole or halve
-
Onions: Thick rings or wedges
Step 3: Toss with Oil and Seasoning
Coat vegetables lightly with olive oil. Sprinkle with salt, pepper, and optional seasonings. Don’t overdo the oil—it can cause flare-ups.

Grill vegetables in batches for 3–5 minutes per side.

Avoid overcrowding—this traps steam and causes sogginess.

Don’t over-oil or over-marinate.
-
Use high heat to quickly char the outside while keeping a bite.
-
Drain watery veggies (like eggplant or mushrooms) with a sprinkle of salt before cooking.
