Ideas for family meal?

i'm getting bored of our normal family meals (fish fingers and mash, toad in the hole, spegbowl, stir fry, roast chicken etc.) and thought i'll try to make something new. the problem is there is 8 of us and 2 of the people are very picky about what they eat. basically one of them don't like beef, turkey, lamb or fish and the other one doesn't like pork which makes it hard for me because we seem to always end up with roast chicken. any dinner sugestions welcomed thanks.
