There are times I only need a little bit of tomato paste in my cooking. So, what do I do with the rest? I freeze the rest! Why waste…freeze and use later 🙂
Here’s how: I use ice tray (any ice tray would do). This is a silicon one. I scoop the tomato paste out of the can into the ice tray compartments,
then I flatten the tomato paste with a spoon. 
I know it kinda looks messy, but that’s okay, it freezes beautifully 🙂
Next, I wrap the ice tray with plastic wrap.
I lay the tray flat inside the freezer. I leave it overnight.
All frozen! 🙂
Next day, I take the tray out and unwrap it. I place a cutting board on the counter and then twist the tray over it. And, down falls out the frozen tomato paste!
Looking good!
I place them in a freezer bag. I seal and label the bag, then I put it back in the freezer until I’m ready to use them. I take out one or two or however many I need, and save the rest for later. 
When I cook meat or veggies, I throw a couple into the pan! I love the taste it gives to my food. Plus, I love to not waste. I feel good about it. Freezing is a good thing! 🙂
Enjoy.
