Sauteed Fish and salsa

I made this on vacation with access to a frying pan, a stove and a fridge/freezer.
It's a quick and easy meal.

Any thin-ish white fish, such as turbot, tilapia, flounder, etc.
Lemonade
Jar of salsa
Can of corn
Two tomatoes
Cooking spray or oil

Saute fish in oil or cooking spray on both sides until mostly cooked through (test in the middle). Add lemonade to the pan until it comes about halfway up the fish. Cook for 5 minutes. Remove fish to a plate and cook liquid until slightly reduced. Pour over fish.

Rinse and wipe out pan. Add spray or oil and add corn. Cook until slightly blackened. Add salsa and diced tomatoes. Cook several minutes until warmed through. Serve with fish.
