Brown ground beef.
About ½ way through add diced onions (1 lg or 2 medium) and celery to the ground beef.
Drain off grease.
Add 1 can of crushed tomatoes.
Use that can to add 1 can of water.
Add a shit ton of salt and pepper.
If you need more liquid, it's to taste; try to keep equal tomato and water.
You need enough juice for the noodles to suck up.
Bring to boil & add noodles.
Keep simmering/bubbly until the noodles are al dente (don't overcook because it's so hot the noodles continue to cook).
