Favorite freezer / crock pot recipes for new moms

Ashley
I'm just barely out of my first trimester, but my sister in law is just starting her third and we were planning a cooking weekend blowout, stocking up before the babies arrive. 
What are some of your favorite make ahead recipes? Something we can toss in the crock pot or oven and not think about until the timer goes off? Pinterest will only get you so far, I'd love to hear about recipes you've made and enjoyed :) 
Breakfast, lunch, snacks, dinner, desserts... I'm open to anything!
