Fish with brown rice and vegetables. I heard that the people who live the longest are either eating tons of fish or like in Italy, there's these old, chain-smoking men living to 90 because they consume so many tomatoes lol. I guess there are a few select ingredients that you wanna have a LOT of! I'm pretty sure garlic is an alright thing to have too.
Something that doesn't have too much fat (it can have a little. Your body needs some), no sugar, not too much salt (again, your body needs some), well, anything from a garden is generally very healthy, so that means salad is a good choice. And it's the best I can come up with, but it gets old very quickly.
