Pour canned diced tomatoes over raw elbow macaroni

If you want to make it work
You can turn it into a simple one-pot tomato pasta:

Put raw elbow macaroni in a pan.
Add 1 can diced tomatoes.
Add about 1–1.5 cups water or broth.
Add salt, garlic, or herbs if you like.
Bring to a gentle boil, then simmer 10–12 minutes, stirring occasionally.
The pasta will cook in the tomato liquid and absorb the flavor.
