As someone who gave up meat recently (and who's always loved meat) I think Burger Kings plant based whopper is wonderful, as is its vegan chicken royale.
Maccy D's McPlant is also excellent.
Congratulations on giving up meat! It's not easy at first is it? I started it as a 7 day challenge, which failed on Day 6 but I restarted it and I never looked back. I did similar with vegan last summer, I thought I'd struggle and it was hard to begin with but thoroughly worth it in my view.
The fact I still do vegan (I did have a slip-up and forgot to check the contents of a sauce at a restaurant recently, which did reinforce my desire to be more careful and up my vegan game) I am proud of. It is a lot easier these days than it used to be, it must be said.
Those burgers you mention, I want to try them but I find it difficult to support such places if I'm honest. McDonald's is easier to support because of their hash browns and cheap but good coffee, but Burger King I try to avoid. KFC, yes their vegan burger sounds nice but occasionally I can smell their kitchen from near the railway station when I pass by and it really puts me off. So do their adverts to be honest, I just can't make myself go into a KFC. If it was that or nothing, I'd have to hastily replan my eating habits and morals to at least try and go in for that vegan burger. When there's choice nearby though, absolutely not!
There's no judgement from me on anyone here who eats meat, I really don't agree with it but I used to eat it so I cannot fairly judge anyone.
Someone mentioned meat substitutes, I have to be honest I do have them semi-regularly but it is on my list of things to change. I've already cut back a long way on such food, so it's an improvement. Before I go and get my evening meal served up, I must give kudos to Co-Op for their surprisingly good vegan range.
Tonight, for example, I'm having one of their frozen vegan burgers with a load of potatoes, runner beans and peas. The burger itself is not too bad, I prefer the Birds Eye Green Cuisine ones I have to confess but these are pretty good. This is in their Gro range, and I must big up their gunpowder chickpea masala and rice ready meal in their chilled range. Surprisingly nice, and yes it's not the same as a chicken tikka masala but I liked it. It's on my list to have again!
Also, Sainsburys' sweet potato katsu curry and rice ready meal is pretty awesome. Expensive at £3, so best bought when on offer (I keep getting 150 bonus Nectar points offers on it, so I buy it fairly regularly) really, but worth a go. There's another ready meal, I think a cauliflower and chickpea curry and rice one, that I haven't yet tried but it sounds excellent. I also recommend their carrot, butternut squash, ginger and turmeric soup in plastic containers in their chilled range. Really nice, although expensive at £2. If you're a lazy vegan like me, it's worth it in my mind.
I do have plans to stop being so lazy and actually make more of my own food, but it's not happening too much yet!
