Sometimes meals are works of art. This one definitely isn't, but it's pretty tasty.
1 lb whole wheat pasta, cooked
1 bunch broccoli, florets chopped and blanched
1/2 yellow onion, diced and sauteed until brown
2 chicken breasts, cooked and pulled
2 c milk
2 T butter
2 T AP flour
1 tsp kosher salt
2 c cheddar cheese, shredded
In a small sauce pan, melt butter. Whisk in the flour. Keep whisking until the butter+flour mixture becomes golden and nutty (at least a minute, but longer if you can stand it). Add in salt and then whisk in milk. Keep stirring and bring to a simmer to thicken. Add in 1.5 c cheese and stir. In a large casserole, toss together the noodles, shredded chicken, broccoli, onions, and cheese sauce. Add in salt and pepper to taste. Sprinkle the top with shredded cheese and bake in a 350 F oven for ~10 minutes if the ingredients were just cooked or closer to 30 minutes if everything was refrigerated.
This is actually really versatile. We just happened to have broccoli, but everything else is basically a pantry staple. Using leftover vegetables and chicken makes this come together even easier.
