My newest favorite tip is:
To brown a very large quantity of ground beef up (slowly of course, so not to burn it). Then drain in and cool into about 1 pound portions in individual containers. Then I pop them in the freezer.
This is SO nice. Their are so many times that I don't make a recipe because I don't feel like browning meat because it's so hot, or I'm just to lazy, or my biggest issue... I forget to thaw it.
It's also really nice, because with how sick I am with this pregnancy, it is really easy for my husband to take out the already browned meat and make goulash, nachos, manwich, etc. for the rest of the family.
