Daily Food Intake

I don't live with/near parents and in-laws who cooks daily. Both Hb and myself work. Feel it's undesirable to always eat out during this period. Hb don't seem to understand the need to be more careful with my diet now, eg. still suggest eating fast food. I tried to cook some food for myself but most times am really too tired to do so. Any tips or suggestions to manage this situation and eat healthily for pregnancy?
