My dcks had this for lunch today (I adapted from the Looney Spoons cookbook). Apologies in advance, I'm not a big measurer!

Home made mac and cheese, with beef and veggies.

Large package of lean ground beef, browned and drain. Set aside.

As meat is browning, cook pasta according to directions.

In large pot, saute 1 diced onion and 2 chopped zucchinis in olive oil. Add ground beef, 1 can (28 oz) of diced tomatoes (I pureed mine) and seasonings. I used garlic, basil and oregano.

Make cheese sauce:
Approx 1/4 c of margarine in pot. Heat to melt.
Add 1/4 c flour. Stir to mix and allow to bubble slightly.
Add 1.5 cup of milk, slowly. Stir continuously until thickened.
Add 1-2 c (depending on how cheesy you like it) of grated cheese. Stir until melted.

Now add cheese sauce into large pot with beef, tomatoes and veggies. Stir until bubbly.

when pasta is cooked, drain, rinse and add to pot with sauce. Serve hot.

***This makes a lot. We are a family of 6, plus dcks. There was enough sauce to do a large casserole for family and dcks, plus do a small gluten free version for mine. I used gf flour for the cheese sauce and cooked gf pasta for mine. My family had leftovers for lunch the next day, as did the dcks, and I had enough leftover for me, as well.
