Garden Chowder

Saute 1 diced zucchini and 1 diced onion in 5T of butter. Stir in 1/3c flour and a little salt and pepper. Add 3 cups of water, 1T adobo, and 1t lemon juice. Boil. Add one can of tomatoes, 1c milk, and 10oz frozen corn. Bring to boil. Stir in 1/4c Parmesan and 2c shredded cheddar. Sometimes I add a little meat--sausage is nice.
