I would buy a bag of rice, beans, pasta shells ( three kinds) and one chicken.
The cost of the rice , beans, and pasta shells would come to about $5.00 and one chicken will be about $5.00
You can eat on this for a while, you do not need to cook the whole bag of beans or rice, you can make at least 4 meals each from them as well as the pasta. With the chicken i would cut it up and place in freezer bags. You can have a hearty meal with beans and chicken, or beans alone, ( seasoned well) rice and chicken
As you can see you can eat for close to a month on this meal plan.
I do not eat a lot of meats when my children come over they always say mom you have no food, if a crisis was to come and we had to eat what was in our homes i could go a year on what i have they would starve or come over my house . ( lol)
