Assuming you ate a decent meal before your ride, you really won't need to eat/drink a lot of calories for a 60-mile ride. Figure 20-24 oz. per hour; less if it's not too hot. For 60 miles, I bring one gel and one stinger waffle. The key (for me) is that meal before the ride - a bowl of oatmeal and banana.
I realize you don't want to be bothered with "performance" foods, but they do work and they're a lot easier to bring/eat on the bike.
