I need help with different dinners?

I'm trying to do something my sister in law told me to do and that's make a menu of dinners for the week. I am having a problem with that because I have not a clue what dinners to make. I have a few thing like meat and gravy with egg noodles, tacos, ham dinner with green bean c., stuffing and mashed potatoes. What are some good dinners that wont break our budget and aren't fancy nasty things. Just some simple family dinners. Please I need your help.
