My aunt has a great recipe for limeade. It actually gets a little weird. It's lemon juice, and lime juice in honey water. Sounds okay, right? But then she puts in sprigs of mint... basil... then celery and cucumber juice! It's practically a drinkable salad. I was really doubtful about it the first time, but now it's one of my favorites.
Ginger is also really, really strong. I would recommend it for detoxing, but it personally does a number on my intestines.
To eat: some kind of broth from real boiled bones. You can keep straining and clarifying it to make a consumme, or you can load it with about a handful of peeled and crushed cloves of garlic, and diced onion. Add the onion last and remove from heat soon after so that it doesn't get too sweet and gooey-- the onions should still have this spicy, crisp crunch, but the garlic should be boiled through. Add salt and pepper to taste, and if you don't have Celiac's or something then have a slice of bread, maybe grilled with a very thin slice of Swiss cheese, to dip into this soup. Or tear the bread up and put it in the soup while it's cooking, then melt a crust of cheese into the soup, but I think the other way is less messy. Quite a simple, frugal meal.
Another simple foodstuff is Monk's Salsa, which can be used as a sandwich spread or a pasta sauce. It's basically a lot of olive oil, used to lightly cook (or even not cook) enough breadcrumbs to make a sauce base. Mix in a lot of tiny pickled onions, green and black olives (I prefer them anchovy-stuffed), salt and pepper, and... one large bay leaf. I learned from trial and error that it's really the bay leaf that gives the whole thing its characteristic flavor, but it takes a few days for the flavor to seep out, so keep it stored somewhere with a bay leaf in it.
