Based on one that my Mom makes, which I think is Uncle Bob's recipe.
Maria ate three bowls of this without pause, and there was enough left for four adults to eat with salad and grilled cheese for dinner.
-1/2 yellow onion, sauteed over medium heat in olive oil/butter mix until softened
-Add 1 clove fresh minced garlic
-Thyme, oregano, marjoram, salt
-Add 3 small red potatoes, diced into bite-sized pieces, peel on
-Add 3 zucchini, quartered and sliced
-Cover and let sweat until potatoes soften and zucchini begins to cook, stirring occasionally
-Add 24 oz homemade chicken stock and bring to a boil
-Reduce heat to low and simmer until vegetables are cooked through
-Off heat, stir in about 2/3 c whole milk
-Puree in blender and return to pot to heat through, salt and pepper to taste.
