This isn’t your average pea soup—Ina builds layers of flavor by sautéing leeks, onions, carrots, and garlic, then simmering dried split peas with a ham hock for richness and a bundle of thyme for aroma. The real star? Crispy kielbasa sautéed separately and scattered on top for texture contrast and smoky punch. It serves 6 as a main dish, thickens naturally as it sits, and reheats like a dream, often tasting even better the next day.
