Use objects instead of arrays.

const app = new Vue({
  el: "#app",
  data() {
    return {
      additionalOptions: [{
        side_dish: {
          0: "Potato",
          1: "Apple"
        }
      }]
    }
  },
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.0.3/vue.js"></script>
<div id="app">
    <div v-for="option in additionalOptions" :key="option">
        <div v-for="(side, side_index) in option.side_dish" :key="side_index">
          <input type="text" v-model="option.side_dish[side_index]" />
        </div>
    </div>
    
     {{additionalOptions}}
</div>
