Easy, delicious, fun (need I say more?).
I've seen some recipes recently that use chirasco and broccoli, so like Rambo said, your mind is the ultimate weapon.
Add-ons? Throw in any veggie you like and or try differnt types of meat. But to keep this one classic, don't scrimp on the olive oil and garlic.
Most recipes call for a uniform cut between size of sausage and peppers, but when using child labor (your kids) just roll with punches and enjoy the variety of sizes and animal shapes you'll get by having your kids help you cook.
It doesn't get much easier than this folks. Serve with rice, potatoes, or toast (or more wine).
In fact, the link to the right had so many good ideas, I included it for more inspiration. Press for ideas.
