I grocery shop weekly so I usually create a weekly meal plan. It isn't always easy coming up with new recipes so I always head to Pinterest when I need inspiration. I usually start my Sunday mornings with a cup of coffee, browse Pinterest then, I'll make a grocery list.
I usually go with recipes that 1) don't have a ton of ingredients and 2) won't take longer than 30 minutes. I do not have time to cook elaborate meals that have a ton of ingredients I can't use often.
