Upon opening a package of Trader Joe's macaroni and cheese, you're met with exactly what makes it awesome—real, shredded cheese piled on top. And not just one, but four different kinds: Havarti, Gouda, Swiss and cheddar. The result? A tangy mac & cheese with a slightly gritty texture and full-on stringy-stretchy-cheesiness that somehow manages to feel like the real deal.
