What meals do you know which aren't too time consuming to prepare (or if they are last for a very long time), are cheap and whose ingredients are easy to acquire?
Bonus if it isn't just mainly carbon-hydrates and if the ingredients don't need to be used immediately (unless the meal itself when done can last for many days).
I recommend Mealime to everybody now. Seriously check it out. Best way i can describe it is; it's like HelloFresh but instead of getting stuff delivered you go grocery shopping. Haha sounds like regular cooking i know. But the way it organizes your grocery list and all the recipes, everything about it is great.
I started using it maybe 6 months ago and have been eating healthier, cheaper, and more varied meals.
If you feel like branching out to your own or other recipes try the app Paprika Recipe Manager.
You can meal plan for the week and then add the week to your grocery list. It even stacks identical ingredients (like if you have 1 red pepper in 3 recipes that week it says 3 red peppers). It also lets you scrape data from websites to build a recipe. Just paste the link in the in-app browser and hit save.
