Crab Salad on Avocado half, BBQ Lobster, Best Ever Cheese Bread, Garlic Green Beans, BBQ Rib steak - tail on, and pineapple custard pie for dessert.
Crab Salad can be prepared a day or two in advance, then put together with the avocado just before serving: same with cheese bread; prepare cheese filling, store in plastic bag in refer, then, spread on bread and throw on grill a few minutes before serving. Meat will be prepared in advance and grilled just before eating. And, of course, the pie can also be made a day or two ahead.
You get much less tired by doing a lot of the advance work, then simply bring it together the day of your planned meal. There's usually enough food left to have leftovers for at least a day!
