In large dutch oven, cook bacon over medium heat until browned and crisp (approx 5 to 6 minutes). Transfer bacon to paper towels to drain. Pour off all but 1 tablespoon of the bacon fat.
Add onion, and cook until soft (approx. 4 to 5 minutes). Add potato, broth, Italian seasoning, cayenne pepper (add a little at a time and taste for your preference), and nutmeg. Simmer until potato is tender (approx. 8 minutes).
Stir in edamame, creamed corn, and half-and-half. Season to taste with salt and pepper. Simmer until edamame is tender.
Serve chowder sprinkled with crumbled bacon.
NOTES: Add 1 to 1 1/2 cups of cubed ham or chicken to make this a heartier chowder. Add cayenne pepper alittle at a time. I use 1/8 teaspoon because I like the chowder to be spicy.
