Preheat oven to 375°F
For 2 minutes, cook and crumble ground beef in large skillet with thick walls. Cook the onions for 5 minutes more, or until brown. Drain the grease.
You can add liquids such as Manwich sauce, chicken broth and undrained diced tomato.
Bring to a gentle boil. Add the pasta to the saucepan and stir.
Let it boil for about 5 minutes. To ensure that the pasta doesn't stick, stir it a few more times. We are simmering the pasta gently so we recommend boiling it for a little longer than indicated on the package. Before you proceed, taste-test the noodles.
Reduce heat to low. Add the corn. To melt the Velveeta, add the cubed Velveeta. Cover the pot with a lid. Gently stir the mixture.
Transfer the mixture to a 9 x 13 inch casserole dish.
Add shredded cheddar to the top.
Bake for 15 minutes covered. Cover and bake for 15 minutes. Serve with cornbread
