I personally don't prep meals for the week. What I like to do is "bulk" shopping and do standard boring trends. So what I will generally do is have breakfast with a cup of almond milk and cereal (not too expensive, especially when you ask friends if you can go to costco with them
Almond milk 12$ for 3 gallons, cereal 3-5$ for industrial sized chex, usually lasts half a month to full month.
For lunch I will have a large bag of lettuce and a choice of low salt lunch meat. I usually side with the chicken on this one, but every once in a while when Im feeling adventurous I'll do salami or pepperoni. 5 dollar bag of lettuce and 5 dollar bag of lunchmeat usually lasts me the week. I try to also grab other veggies as well; carrots, celery, broccoli, etc. Problem is, these guys are expensive and go bad quickly.
For snacks, I have a bag of almonds on my desk. I usually just pop a couple in my mouth and it satiates the hunger.
For dinner, I try to go light and do low sugar yogurt mixed with a spoonful of almonds. I usually get my yogurts 4 for 4.
I treat myself on fridays saturdays and sundays, I bake skinless chicken and steam broccoli.
How about you, Any tips on how to live frugal?
