Saving to SQLite database is crashing android app

I'm working on an android app that saves a couple of text field inputs to a SQLite database. When I try to do so though, the app crashes and I don't know what exactly it is I'm doing wrong. Though I'm certain the error is coming from the lines where I open and write to the database.

// Instantiate onClickListener for addFoodItemSubmitButton
addFoodItemSubmitButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        // Read user input for food item
        String foodItemName = ((EditText) findViewById(R.id.foodItemNameField)).toString();
        String foodItemExpirationDate = ((EditText)findViewById(R.id.foodItemExpirationDateField)).toString();

        // Insert values into SQLite Database
        SQLiteDatabase db = openOrCreateDatabase("FoodItemDB", MODE_PRIVATE, null);
        db.execSQL("INSERT INTO FoodItems VALUES(" + foodItemName + "VARCHAR" + foodItemExpirationDate + "VARCHAR" + ")");
        db.close();

        Date expirationDate = stringtoDate(foodItemExpirationDate, "/");

        // Set notificationTask timer
        // TODO: add notificationTask that triggers before expirationDate
        //Timer expirationTimer = new Timer(notificationTask, expirationDate);

        Intent intent = new Intent(view.getContext(), MainActivity.class);
        startActivity(intent);
    }
});

This is the listener class for my submit button for the form.
