My never-fail fish chowder

This chowder is one of my family's absolute favorite meals. Any kind/amount of fish and any availability of veggies added in makes variation. Skim milk keeps it healthy too!

Here's how I make it

Put a little canola oil in a large saucepan, cube up 9 or 10 potatoes and an onion in 1/2 in cubes. Heat up and cook for ~5 min or so. Add 2 c water, some salt and pepper, 1 Tbsp Old Bay seasoning, cover and cook for about another 6 or 7 minutes, till potatoes are softened. Add other veggies (frozen, canned, fresh) that you want (cubed squash makes a good addition too!), add 4 c milk and heat up, add fish too (whatever kind you have!--don't even have to cook it, it'll cook in the liquid) Simmer for 5 min or so. Mix 1 c cold milk with 1/3 c flour, whisk together, then mix it into the hot chowder. Return to boil, cook for another 5 min. Serve yummmmmmmmmmmy!!
