Did anyone else find particular resonance when Homer Simpson was going to climb that mountain and bought a kitchen gadget (that looked a little too much like a sausage grinder for comfort) that made food into bars. He dumped a plate of spaghetti and meatballs into it, and I laughed with the comfort of knowing that if I could, I might do that too.
I eat a lot of food in bar form because of a (likely perceived) lack of time to cook. I'd like to point out a couple bars you might not have heard of, though.
I just noticed Skout bars in the school canteen and the local crunchy food stores. They're locally made (Portland, OR represent!) and are like Clif bars in texture, but have an ingredient list more akin to a Larabar. They're date and grain (usually oat) based, sweetened with apple juice concentrate. They're pretty tasty, and don't have that greasiness that Larabars sometimes have.
Full disclosure: I know the founder of this company from back home. The Core Method replacement bars are HEAVY. Since I bike to hell and back, I'm okay with eating one of these hyper-caloric, mostly raw monsters, but I wouldn't recommend it as a snack for less active folks. It's decidedly a meal replacement. The raw cashew and cacao is good, I'm less crazy about the raisin one. ONLY the Defender bars are vegan. The Warrior bars contain whey. (Disappointing considering Corey, the founder, was the first vegan I ever met - I think he's well off the wagon.) In Portland, I've only found them at Whole Foods, but that suggests they're widely available.
