Freezer crockpot meals. These are all healthy meals from what I had a chance to look over. No cans of soup or cream cheese, etc... The price per meal she works out is under $4 and she prepares meals for up to 10 weeks.
What I love about this recipe for freezer-to-crockpot chicken fajitas in particular is that it's very healthy. The chicken, peppers, and onions are all fresh and you create your own simple sauce by adding apple cider vinegar, honey, and seasonings.
