I grilled a 3 lb tri tip, stuffed portabello mushrooms and corn on the cob. They were paired up with a Mixed greens salad and home made garlic bread.
If you haven't tried tri tip I highly recommend it. The trick is to get a 2.5+ lb roast and seer it on both sides then cook it at 325 until the internal temp rest 130-135. Wrap it with foil and let it read for at least 15 minutes before cutting and serving.
