I'm the same :) I have a pretty awesome recipe I use for bean burger patties that are very cheap and very delicious. my SO loves them too

I guess there just isn't really a way to replace something like salami or bacon in a self-made vegan way, same goes for cheese (slices) unless you're into preparing vegan mozzarella or something by yourself, so I'm fine getting those. Vegan minced meat is also something I buy for bolognese, lasagna, or chilli - you can substitute it with tofu too, which I do sometimes, but it's just less of a hassle and doesn't cost too much at Lidl.
