You have to destroy and re-initialize the TomSelect to have the select updated.

Ps: Alternatives to this approach, TomSelect API Docs offers various options. You can use removeItem() function instead, then add them back based on the condition. In my humble opinion, I think this is a better approach than the way you're currently clear/append the option tags

const mealOrder = document.getElementById("orderMeal")

// Initialize TomSelect and refer the instance to a variable
let mealTomSelect = new TomSelect("#appendOption", {
  sortField: {
    field: "text",
    direction: "asc"
  }
});

mealOrder.addEventListener('change', function() {
  // you have to destroy the TomSelect instance first
  mealTomSelect.destroy();

  switch (this.value) {
    case "1":
      $("#appendOption").empty();
      $("#appendOption").append(`<option>Hot Dog, Fries and a Soda</option>` +
        `<option>Burger, Shake and a Smile</option>` +
        `<option>Sugar, Spice and all things nice</option>`);
      break;

    case "2":
      $("#appendOption").empty();
      $("#appendOption").append(`<option>Pizza, Popcorn, Burger</option>` +
        `<option>Burger, Chicken Wings, Soda</option>` +
        `<option>Random</option>`);
      break;

    case "3":
      $("#appendOption").empty();
      $("#appendOption").append(`<option>Soup. Carbonara, Coke</option>` +
        `<option>Chocolate Cheese Cake, Coffee</option>` +
        `<option>Random</option>`);
      break;
    case "0":
      $("#appendOption").empty();
      $("#appendOption").append(`<option>Select</option>`);
      break;
  }

  // Then re-initialize it
  mealTomSelect = new TomSelect("#appendOption", {
    sortField: {
      field: "text",
      direction: "asc"
    }
  });

})
