Most people will find that a heavy breakfast is a no go. It is hot and I never eat much at one meal. We usually start with yogurt and fruit, maybe a breakfast roll or croissant, or cereal and juice. Mid morning snack is usually laden with sugar (Lorna Doone peanut butter cookies) or similar. Last trip we did lunch out more than dinner. Sandwiches work well and can be fixed ahead and devoured underway. Veggie sticks for afternoon snack with some kind of dip and some mixed nuts. Dinner is always grilled meat, salad, garlic bread etc. I NEVER COOK in the galley. Too hot, messy and totally unnecessary. I am on vacation too.
