Easy Meatless Recipes
I know some families observe a weekly meatless dinner like Meatless Monday for a variety of reasons. Perhaps your family is taking steps towards a completely vegetarian lifestyle altogether. In either case, you may be looking for more recipes that don't have meat but still appeal to kids.
It's also possible your family practices abstaining from meat during Lent like our family does. In this case, you might be ok with some fish recipes for Fridays.
However you need to define "meatless" for your family, I've got some great kid-tested dinner ideas for you here.
