I would suggest that you write down how much money you have set aside for food each month, and decide what foods are essential....:::those would be your basics. Then build on that list with other foods that you really enjoy, and are healthy for you...::lastly, whatever money you have as your difference - take that $ and splurge on something special....::for me it is raw honey, or Merlot wine, or very dark chocolate...Lol. I have a family of 6 to feed and it is so important to maintain a healthy grocery list for them. One of our staples is good whole wheat bread, whatever fresh fruit is in season....right now is crisp & sweet...:::and we love home made granola....:::from scratch.
Celery & carrot sticks are another staple, good source of fiber and lo cal.... I keep both around for munching. Plain yogurt is an awesome versatile food that acts as a dressing, topping for many salads, steamed veggies even a taco topping to replace sour cream!
I hope that this helps. As for the strawberries, I would stick to eating whatever fruit is in season...try new fruits.
