For fresh corn, use a sharp knife to cut the kernels off the cobs. Set them aside.
In a large pot, heat up oil then cook onions and green peppers until tender but not brown.
Stir in corn, broth(water), and potato cubes. Bring to a boil, reduce heat, cover and simmer for 10 to 15 minutes, stirring occasionally.
In a bowl, combine flour, salt, and black pepper. Stir in milk into the flour mixture. Add into the pot. Stir and continue to cook until slightly thickened and bubbly. Cook for another minute or so.
Brown the chopped bacon or ham in a pan with hot oil. Use that to garnish the bowls of corn chowder.
