8. Trader Joe’s: Joe’s Diner Mac ‘n Cheese

Type: Frozen
Ease of Preparation: 
10/10  (a few minutes in the microwave)
 7/10 (360 calories/serving; nothing artificial)
Nostalgia Factor: 

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.
