Options for an almost turned bag of fresh spinach

Title says it all. My parents visited this past weekend, and my mom took my 1/4 empty fridge as a sign that she needed to fill it up. I enjoy not having a packed fridge, for us it means less food waste. We use up what we have before buying more. Plus it’s starting to be farmers market season, so I wanted to use my grocery veg and get local fresh veg this coming weekend. Anyways, now I have a bag of Popeye’s Spinach, and we don’t each a ton of fresh spinach. What can I do with it? Freeze it? How? If possible I’d like to freeze it in 2 cup increments so I can pull it out for lasagna or dips.
