3 ounces pancetta or bacon, chopped fine
1 medium onion, chopped fine (about 1 cup)
1 celery rib, chopped fine (about 2/3 cup)
4 medium garlic cloves, minced or pressed through garlic press (about 1
heaping Tablespoon)
1 t. dried oregano
1/4 teaspoon red pepper flakes
3 anchovy filets, minced to paste (about 1 teaspoon)
1 can (28 ounces) diced tomatoes with liquid
1 piece Parmesan cheese rind, about 5" x 2"
2 cans cannellini beans, rinsed and drained (15.5 ounces each)
3&1/2 cups canned low sodium chicken broth
Salt
8 ounces small pasta shape, such as orzo, tubetini, ditalini, or
conchigliette
1/4 cup chopped fresh parsley leaves

Heat oil in large Dutch oven over medium high heat until shimmering but not smoking, about 2 minutes.
Add pancetta and cook, stirring occasionally until beginning to brown, 3-5 minutes.
Add onion and celery; cook, stirring occasionally until vegetables are softened, 5-7 minutes.

Add tomatoes, scraping up any browned bits from bottom of

Refer to package instructions to better estimate pasta cooking time).
Discard cheese rind.
Take Off heat, stir in 3 T parsley; adjust seasoning with salt and pepper.
Ladle soup into individual bowl; drizzle each serving with olive oil land sprinkle with a portion of remaining parsley.
Serve at once.
Pass Parmesan cheese separately.
Note: I made this soup only once before. It was good.
However, it does not hold well, as the pasta absorbs the liquid.
The soup can be made in two stages.
Once the beans are simmered with the tomatoes, before the broth and water are added, the mixture can be cooled and refrigerated for up to 3 days.
When ready to complete the soup, discard the Parmesan rind (otherwise it will become stringy), add the liquid, bring the soup to a boil and proceed with the recipe.
