Can I reuse a Classico pasta sauce glass container for oatmeal?

Of course you can.

Just wash it out really well. I reuse jars all the time.

Yes you can. Wash it out really well & make sure it is thoroughly dry before adding the oats to it.

Yes. Glass is the best. How is this going to save you “lots” of money?

@Sagacious I will save money by not purchasing glass mason jars and the cab fare to go look for them. $10 is a lot of money to me.

I used to save all my glass jars too. I couldn’t bear to throw them away. They’re so Useful.
Then I learned they can be recycled. What a weight lifted off of my shelves! But I still save a few select ones.
