Mac & Cheese isn’t something I have very often, but I’ve tried quite a few frozen and microwave mac & cheeses.
For frozen, my pick would be Devour White Cheddar with Smoked Bacon. There’s a Beecher’s mac & cheese I’ve been tempted to try, but I haven’t been able to get past the price of it.
Of the microwaveable bowls or cups that I’ve had, Cracker Barrel Sharp Cheddar has been the best of those.
