Halloumi, beer can chicken and corn.

The only dessert I know how to make... grilled pineapple with nutella and mascarpone. Thanks, Giada!

these are the best steaks i've ever had:

Although I'm vegetarian 98% of the time, those 2% occasions are almost invariably due to the temptation of a grilled hamburger resplendent in basil/pesto. An instant read thermometer is an essential tool to ensure the center has reached a safe temperature.

Later in the summer: straight-up veggies. I especially like green beans (with olive oil).

Also peaches with a cinnamon-sugar glaze-- I've seen it done on tin foil on the grill, but skewers would probably be better.

Kebabs.

Oh, and stuffed hot peppers (halved, seeded, with ground beef/pork and melty cheese).

In the meantime, while waiting for these things to grow, I second the beer can chicken and pizza ideas.

Can you tell I've been thinking about grilling season all winter?!

Easiest and tastiest? Shish kababs! Get some bamboo skewers, and spear some pieces of bell pepper, button mushrooms, lamb, pearl onions, and cherry tomatoes, all previously marinated in oil, vinegar, and fresh herbs. Perfect every time.

WOW, I almost wrote in this exact same question this morning after acquiring a grill this weekend. Keep the suggestions coming!

Mark Bittman's grilled split chicken. Over a charcoal grill it's hands down the best roast chicken you'll ever have and it's dead easy to make.

Start simple: Get some Jer's rub and do a steak 3 minutes on a side, twice."

Kababs are an excellent idea. Grilled peaches for dessert. Top them with a little molasses and maybe some whipped cream. Awesome!

I agree with a lot of the previous suggestions - fruit, chicken, veggies are all a great place for a grilling newbie to start. Another favorite in our household is steak. No recipe needed - I just do salt, pepper, and a little olive oil. Err on the side of rareness, because you can always throw it back on for a bit if it's underdone, and it will continue to cook when you pull it off. I love a good ribeye with grilled asparagus, onions, and mushrooms.

Cut slices of squash and zucchini (cutting down the length of the veggies to keep nice wide pieces that won't fall through the grill) and marinate them in italian dressing or a favorite vinaigrette for 10-15 minutes then throw on the grill. Flip once, cook to desired tenderness. Usually doesn't take longer than 10-15 minutes on a hot grill.

Grilled corn on the cob is super easy and so delicious.

A personal favorite at our house are bacon-wrapped jalapenos. Slice peppers in half and remove seeds (I wear gloves and use a spoon). Fill pepper halves with cream cheese and wrap with 1/3 or 1/2 piece of bacon, then thread onto a skewer. Grill until bacon is done/crispy. A quick tip for filling the peppers: put the cream cheese in a baggie and snip the corner to "pipe" the cheese into the pepper halves.

I make this Cedar plank salmon all the time! Love it!

Funny...I was in a similar position about a year ago. I started this blog to document me cooking my through one of Weber's grilling cookbooks.
