On day 6, hang out with Bea. This will be the third friend hangout of your Playthrough.
You'll go grocery shopping with Bea, and she will ask you to pick out groceries for dinner.
There are multiple ways to get a good dinner, but the one I (and other guides I've seen) went with is:
- Cream of Chicken Soup
- Mac'n Cheese
- Biscuits
- Chicken
You will get the Achievement after having dinner with Bea and her dad.
