Peanut Butter
As cashew and almond butters continue their quest for world domination, we'd like to take a moment to remember the classic that started it all: peanut butter. Sales may be declining, but our love for this workhorse sure isn't. Peanut butter tends to be cheaper than its trendier competitors, and can elevate practically any breakfast, from oatmeal to yogurt to smoothies.
