Ingredients:
4 T. flour
2 t. sugar
1/2 t. pepper
1 t. salt
4 T. butter
2 T. grated onion
1/2 pt. sour cream I use Greek yogurt
1/2 c. milk
2 cans French-sliced green beans, well drained, sometimes I use 3 cans
1/2 lb. grated Swiss cheese
2 c. corn flakes
2 T. melted butter
Directions:
- Melt 4 T of butter in saucepan. Stir in onion; fry till tender.

A recipe that starts with sauteing onions in butter MUST be good!
P.S. I am making a double batch, so yours won't look like this much. - Add flour, sugar, pepper, and salt. Stir till bubbly.

It'll look like PlayDoh.
P.S. Remember, I'm making a double batch so this is twice what you'll have. - Add sour cream or Greek yogurt and milk. Stir till thick.

Mine was a bit too thick, so I thinned a bit with a little extra milk. - Butter casserole dish or spray with cooking spray.
- Layer beans, cheese, sauce; repeat.

Beans first, and then the cheese!

Estimate about half the sauce for this layer.

Then repeat with beans, cheese, and more sauce. Don't forget to spread it around. - Crush corn flakes and combine with melted butter. Sprinkle over top.

I like lots of crunch goodness, so I use more corn flakes and butter than the original recipe calls for. - Bake at 400* for 20 minutes.

Baked up perfectly in my little toaster oven! It's bubble and gooey under that layer of cereal.
