Feedback messaging (toast) for multiple items added to cart

I'm currently working on design customisations of the woocommerce cart for a hotel selling services and products. Most products are single selection, while some have multiple sub-products, example, a buffet with veg and non-veg options each having quantity selection and a common ADD TO CART button.

My question is, when multiple products are added to cart, what should the feedback messaging be?

• Multiple toasts each with '[sub-product name] has been added to your cart'
• Single toast with '3 items from [product name] have been added to your cart'. (what should it say when a single sub-product is added?)
• Also for the messaging I'd like to think of alternatives for the word 'item' or 'product' since they sell a lot of services.

Thanks for the feedback!
