Meal Tracking and Planning Project

Hey all, first post here.

I am undertaking a challenge to eat on $4 a day for a month (while still getting 2,000 calories a day and eating relatively healthy). I want to pull together an excel sheet to help me plan and track these meals. I have used excel for a while to track various aspects of my life but I never got too deep into it.

So I went shopping and bought about twenty items for which I recorded name, price, price per serving, and calories per serving.

I am imagining a box for each day split into 3 meals. Under each meal would be an entry for number of servings and a drop down menu for food items, which would autofill calorie and cost information based on the food item you chose and number of servings you input. Also I would like to display totals for calories and costs.
Something like this except I did this all by hand and I would like it to be more autonomous.

I know I eat random stuff, but.... I'm in college...
This is what my reference list looks like:

Any and all criticism welcome. Thanks!
