My Mac and Cheese Pie

I found an old recipe of my late mother's and was inspired to make a version of it.  She put a sliced tomato in hers.  Making a cheese sauce is always a challenge for me as I get impatient.  You have to add the milk a little at a time and it will thicken nicely as you stir.  Of course anything with a lot of cheese tastes delicious.  Here is my recipe:

2 1/2c elbow macaroni

2 c  milk

1 tbs flour 

1 tbs butter

2 c cheddar cheese

2 handfuls grated cheese

1 tbs butter cut up,  to dot over the pie

1 tomato sliced

1/4c breadcrumbs

Cook macaroni in salted water.

Melt 1 tbs butter in a medium saucepan, mix in 1 tbs flour.  GRADUALLY add milk  a little at a time.

The roux will thicken in about 8 mins as you stir.

Add cheese and stir till melted, add tomato.

Line a  9 inch pan with parchment paper, add macaroni,

pour cheese sauce and mix in.

Sprinkle 2 handfuls of grated cheese over top.

Then prinkle breadcrumbs over top, then dot with butter

Bake at 325F for 20 mins, check at intervals to make sure it is not burning, it should just be nicely browned on top.
