When planning your meals for the week, choose recipes with similar ingredients — those that call for similar vegetables, grains, proteins, etc. My total receipt for 15 meals amounted to $60 ($4 per meal), and I didn't skimp out on organic ingredients.
So there is no lugging of ingredients or measuring cups and spoons, give yourself an hour each morning (or the night before) to prep the ingredients and divvy them into plastic Tupperware. This makes for easy dumping and microwaving action! The time frame is a commitment, I know, but it's like consolidating three 20-minute meals in one go. I enjoyed the exhilarating dash to finish the prep and make it out the door on time every day.
