Split pea soup has been around for centuries - and for good reason. This recipe is packed with plant protein, boasts a hefty 17 grams of fiber and contains a range of cancer-fighting phytochemicals. Garlic, onion and herbs add a boost of flavor without a lot of added salt. In fact, cooking this up at home bypasses the excess sodium found in canned versions. Pair with a leafy green salad for a balanced, cancer-protective meal.
