Meal planning is the best way to stay mindful of what you are eating and what you are purchasing at the grocery store. Set aside 30 minutes each week to focus on 7 dinner recipes for the week. Repeat favorites often and try to make one meal that can carry over to the next night for leftovers to make it easier during the week. Also learn to try new recipes to keep the meals fun and interesting. There are many great allergy friendly cookbooks, but also learn to use recipes from other cookbooks and modify the ingredients to fit your dietary needs.
When you get into a routine of meal planning, streamlining your pantry and refrigerator, and then shopping only one or two times a week, it is freeing. You will feel calm and in control of mealtime! Take it one step further and do meal prep early in the day.
