Menu Variety - Thoughts?

So we met with our caterer and loved the food. We are having a semi-formal wedding and want an untraditional menu (because of preference, not cost). We decided on tacos and sliders!

I know some might think our menu isn't formal enough, but what I'm concerned with is variety. Do we have enough variety? Add another side? Our caterer thinks we have plenty, but I'm unsure. We also said he would work with any vegetarians ( We have 3, no vegans). Any feedback is welcomed!
