SAUTÉ VEGETABLES: Heat oil, butter, and crushed red pepper for a minute over medium flame in an 8-quart soup pot. Add onion, garlic, carrot, and celery. Stir in spices, herbs, and bay leaf. Cover and cook, stirring often, for 7-8 minutes or until softened. Pour in wine and cook two minutes or until wine is nearly absorbed.
ADD STOCK/BRING TO A BOIL/ADD POTATOES, PASTA, AND TUNA and reduce to simmer for about 10 minutes or until nearly tender. Taste and adjust seasonings.
SAUTÉ ASPARAGUS TIPS IN A SKILLET/SET ASIDE: Meanwhile, heat a small skillet over medium-high flame with a tablespoon of olive oil. Add asparagus tips, season with a sprinkle of salt and pepper, and sauté, stirring, for a minute or two. Remove from heat and reserve. (In a pinch, skip the sauté, slice them thinly, and use raw.)
ADD THE OTHER ASPARAGUS PIECES, CORN, AND PEAS TO THE SOUP POT and simmer until all vegetables are tender—another 3-4 minutes. Stir in milk mixture and cook at a low simmer, stirring often, for a few minutes until thickened. Do not boil. Taste and adjust seasonings one last time.
SERVE HOT WITH GARNISHES: Ladle into bowls and top with reserved minced parsley, grated Cheddar, and reserved sautéed asparagus tips. Serve with oyster crackers or saltines.STORAGE: Store tightly covered in the refrigerator for up to 3 days. Reheat gently over low heat without boiling. Do not freeze or, if you do, freeze the chowder before you add milk. Thaw, heat, and whisk in milk slurry at that point.
