Crepes with Savoury Filling (Elsie)

I'm making an assumption that everyone knows how to make crepes.
I'm just listing the ingredients here.
1/2 cup flour
1/2 cup milk
1/2 tsp salt
1 egg

 This was another recipe I concocted when money was tight and I was trying to figure out what to make for dinner with odds and ends left in the fridge.
1 can tuna canned in water, drained ( minced cooked chicken works too)
Add finely chopped onion, red or green pepper,celery,mushroom, apple, bits of leftover cooked veggies.
Water chestnuts are good too. Use some or all of the items listed here.
Mix all this together with cream of mushroom or cream of celery soup thinned with a little milk.Reserve about 1/3 of the can for topping.
Spread some  filling along the edge of crepe and roll up. Place in a greased 9x13 baking dish.Repeat with the rest of the crepes. Add a bit more milk to the remainder of the soup and pour evenly over the crepes. Place some pepper slices on top for garnish. Bake @350 until heated through about 30 minutes.

If anyone knows of a healthier substitute for cream soup please let me know.
