If you wish to alter the display of the WPPizza menu items – alongside many other layout elements – from the installed default, use any of the options below
In 99% of cases a combination of the above the should let you adjust the layout as you require to fully integrate with your chosen theme I would think (make sure you test any changes you make on multiple devices ).
However, if you still feel the need to modify the templates themselves please refer to the templates documentation
in your wp-config.php you will find a line that reads (most likely) like this:
define('WP_DEBUG', false);
REPLACE this with (or if it does not exist simply add the below)
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);/*this should NEVER be true for production sites*/
Note: this MUST be before /* That's all, stop editing! Happy blogging. */
Which will generate a file “wp-content/debug.log” if and when any errors are encountered.
Check this file for errors if you need to find out where things might go wrong
Note that in many cases a lot more information/help is available in the help screens of the plugin 
If you see some “500 Internal server errors” in there, check your server error log. In many cases these are caused by uploading a plugin with the wrong permissions – especially if you add plugins by ftp instead of using the standard wordpress plugin installer. You should also aim to fix any other javascript errors you may have, although some might be more problematic than others
If you have issues with WPPizza – or WordPress in general for that matter – I would highly recommend the following resource to narrow down where your issues might be
As I could not say this any better, forgive me for simply providing the link above. I would however especially recommend the “Troubleshooting Plugins” section about 2 thirds down on that page.
Of course, if you have followed the recommendations on that page without being able to solve your problem and still have issues with WPPizza, please get in touch via the common channels (forum, contact form, emails)
The below filter will *only* apply to emails (as emails need style declarations to be added inline). For Print templates, use the css input in WPPizza->Templates->Print in conjunction with your browsers element inspector
@param: array
@return: array
add_filter('wppizza_ingredients_filter_email_styles', 'myprefix_ingredients_filter_email_styles');
function myprefix_ingredients_filter_email_styles($styles){
/*
default styles passed on to $styles parameter are currently as follows (though might get tweaked in the future)
$styles = array();
$styles['ingrinfo'] = 'white-space: initial; margin: 3px; line-height: 130%;' ;
$styles['ingr_item'] = 'font-style: italic;' ;
$styles['ingrinfo'] = 'white-space: initial; margin: 3px 3px 3px 20px; line-height: 130%; font-size:85%;' ;

/*
if you want to - for example - increase the font for each ingredients in your emails to
120% instead of the default of 85%, you can do this
*/
$styles['ingrinfo'] .='font-size:120%;';
/*
or you could override the whole declaration , removing any margins etc and setting font to 14px
*/
$styles['ingrinfo'] ='font-size:14px;';
return $styles;
