That's easy. It's the little wedgie of cheese that gets stuck on the pan or box after slicing it. With a little luck, there's a good tidbit of topping left on it, too.
Likewise, the best bite of cake? For me at least, it's little scrapey parts, mostly frosting, left over. Clean that up right, that's what I always say.
Or the best chip chomp? When there's just a few little shards left, down in the bottom, which makes them perfect from sliding right from the bag into your mouth. Yum.
So...salad. What's the tastiest part of salad?
Also easy. Gotta be the goodies you put on top.
Nothing against spinach or lettuce or shredded carrots or grape tomatoes or pepper slices or any other veggie part of salad. That's some wholesome goodness. They're what makes a salad good. But what dermines if a salad is goood is the toppings and munchies, especially if you're not one for salad dressing (like me).

Couldn't tell ya. I ate it on eggs instead.
To be fair, that's one of the recommended uses printed right on the front of the bag, along with "vegetables" (presumed of the non-salad-esque variety) and cream cheese bagels. We were having eggs for dinner. Had to write a review. Gotta do what you gotta do. And as much as the bag also suggested it was a great idea, I didn't want to eat a little baggie of seeds all by itself.
And yup, baggie. Inside the main bag there's eight seperate single serving size sacks o' seeds. Each contain about the same amount of almond slivers, pepitas, sesame seeds (white and black), and nigella seeds with a slight little spicy kick from crushed red pepper. As you could imagine, there's nuttiness and a little earthiness, a good bit of sesame, and even almost a little bit of a onion-y to not quite garlic-y essence to the mix, backed by some heat. In some ways, it kinda seemed like the everything but the bagel spice blend, minus the salt but plus the nuts and pepitas. The whole mix is appropriately crunchy and munchy, with a varying texture that did seem a little odd perhaps on eggs - almonds on eggs? seriously? - but I could tell it'd work well in a hearty salad, or on some roasted chicken or grilled veggies, or in several kinds of ways I haven't quite come up with yet but perhaps you have.
It's $3.99 for the big bag, eight servings in there, so basically 50 cents a pop for a small handful of stuff. It'd probably be more economical to make your own if this blend is one you particularly enjoyed, so there's a slight knock. As always, there's a premium for convenience.
Not much else to really say. So, for some, here's the best part of the review: the end.
