UK - vegetarian meatballs, which to choose?

I, along with two others, are planning a menu for a four-day summer camp for gymnasts (aged 8-16). One of the menu ideas is for spaghetti and meatballs. We do have a tight budget, the gymnastics club runs as a charity...

My family doesn't really like veggie meat replacements (we aren't vegetarian but do not eat much meat, legumes seem to be the most accepted), so I am unsure which vegetarian meatballs would be best. I have found these online at supermarkets near me, and any opinions on which are good would be so helpful.

• Aldi Plant menu meat-free meatballs
• Plant Based by ASDA Meat-Free Meatballs
• Tesco Plant Chef No-Beef Meatballs
• Morrison's Tivall Vegetarian Meatballs

Thank you!!
