Name: Bacon Chicken Corn Chowder
Ingredients: 1 yellow or sweet onion, diced; or 3 green onions, sliced; About 1/3 cup celery, diced (about 4-inch section; mine had leaves, which add wonderful flavor and nutrition); 6 medium-sized potatoes, baked (I used Russett, each about 4 inches long); ½ cup gluten-free chicken broth/stock; 1 ½ cups milk (dairy or non-dairy, I used unsweetened almond milk); 2 cups turkey (or chicken), diced; 1 can cream-style corn or equivalent amount of regular canned corn, frozen corn, or roasted corn kernels (see notes); 2 tbsp gluten-free all-purpose flour (optional); 4 slices bacon, diced and cooked (see notes)
