Quick and easy meals

For my 1yo and I.

My fiance works swing shift so hes gone during dinner time.

Im struggling on what to make for dinners for just her and I. I save the bigger dinners that take alot of work (enchiladas, tacos, burgers, etc.) for when we are eating as a family. Im running out of ideas. I try to keep her and I on a healthy diet so please list healthier ideas!:)
