Honestly simplicity is the best tool to eat healthy
Start by buying a rice cooker - simple and easy to use,
Buy pre-washed vegetables (spinach, cherry tomatoes etc)
Frozen vegetables such as broccoli, asparagus, strawberries, blueberries, raspberries etc
If you buy chicken breast or extra lean ground beef, chicken or turkey dedicate one day a week and cook everything in advance, for me it only takes 2.5 hours to cook everything and put it in small containers, these work wonders and save you money
Also getting into the habit of reading the food label it's a great tool, stay away from foods that are high on sodium and high sugar content.
Go and the web and search easy to cook recipes, as I said, simplicity is the best tool..
Good luck man..
