Cannot make json valid for recyclerview

I'm trying to JSON using Gson and recyclerview. My JSON isnt completely valid. In my JSON, the food field has only one of the string quoted leaving the other unquoted. Kindly see my JSON below...

[
    {"quantity" = 2, 
    "price" = 15, 
    "food" = "Fried" Rice}, 
    {"quantity" = 2,
    "price" = 20,
    "food" = "Rice" and Stew}
    ]

You can see that Fried is in quotes and Rice isnt in quotes, likewise the same for Rice and Stew in the other too. Initially it was like this ...

[
    {quantity = 2, 
    price = 15, 
    food = Fried Rice}, 
    {quantity = 2,
    price = 20,
    food = Rice and Stew}
    ]

My activity class code...

Bundle extras = getIntent().getExtras();
    if (extras != null) {
        String listOfFood = extras.getString("foods");
        listOfFood = listOfFood.replaceAll("([\\w]+)[ ]*=", "\"$1\" ="); // to quote before = value
        listOfFood = listOfFood.replaceAll("=[ ]*([\\w@\\.]+)", "= \"$1\""); // to quote after = value, add special character as needed to the exclusion list in regex
        listOfFood = listOfFood.replaceAll("=[ ]*\"([\\d]+)\"", "= $1"); // to un-quote decimal value
        listOfFood = listOfFood.replaceAll("\"true\"", "true"); // to un-quote boolean
        listOfFood = listOfFood.replaceAll("\"false\"", "false"); // to un-quote boolean
        Log.d(TAG, "onCreate: "+listOfFood);
        GsonBuilder builder = new GsonBuilder();
        Gson mGson = builder.create();
        List<FoodOrder> posts = new ArrayList<FoodOrder>();
        posts = Arrays.asList(mGson.fromJson(listOfFood, FoodOrder[].class));
        adapter = new RecyclerViewAdapter(FoodsOrderedActivity.this, posts);
        recyclerView.setAdapter(adapter);
    }

I need the food field that has Fried Rice to be inbetween quotes as one and the same for rice and stew or if theres a workaround, I would like to know.

Thank you
