Well you have to be careful with what you make and re heat especially with baby now. But Def stie frys , protein meats and veggies , also fruit bowls(fresh made) . I just usually pack what I ate the night before for lunch or do a hot sub in the am before work and just heat at work.
Good morning, I am 6 weeks as well with my first child. Honestly the biggest help for me has been Pinterest.
Pregnancy does and Don'ts by Elisabeth Aron so far has been the best book I came across. This book was suggested by my doctor (written by a doctor as well).
As a side note, the more books you read the more you realize how inaccurate most of them are :-)
Are you looking for healthy meals or just the normal stuff doc asks pregnant women to stay away from.
