Not sure where you're located, but in the UK the supermarkets stock stuff like this: https://groceries.aldi.co.uk/en-GB/p-plant-menu-ultimate-no-... https://www.trolley.co.uk/product/linda-mccartneys-2-vegetar... They taste delicious and are absolutely competitive with meat burger prices.
Aldi sells minced beef at literally half the price of the veggie burgers you linked to: https://groceries.aldi.co.uk/en-GB/p-ashfields-25-fat-britis...
If you go for lean mince then you're at exactly the same price range: https://groceries.aldi.co.uk/en-GB/p-ashfields-british-extra...
That's lower calorie than the veggie burger, but you still have to do the prep yourself.
Or you can go for the quorn mince which is much leaner than all the above and costs less than the lean beef mince: https://groceries.aldi.co.uk/en-GB/p-quorn-mince-500g/501950...
