Yup OP, I'm with you, and we've been lucky enough to have largely been in lower tiers before lockdowns, so have been able to occasionally eat out (although we tended to go places where we could sit outside).
During the first lockdown, we had a few themed meals (based around trips we had cancelled), so Spanish week as DD was supposed to have had a school language trip, trying out some new ideas - churros were a massive hit! Italy week, US week. They key was thinking about what we definitely would have eaten when there and recreating it at home - was good trying new techniques.
During this lockdown, I'm so over cooking all the time, so last week we tried a couple of Mindful Chef meals, this week we're trying Gousto. My kids are teens, so I've asked them to choose 2 meals they'll both eat (DS is fussy), and asked them to cook as well. Last night honestly felt like such a treat when Inpoured my selfish a drink and read my book. I did the clearing away and washing up, that seemed only fair, but seeing as most days I have to do both, it felt a real treat.
And yes to local restaurants doing takeaways, our local pub is doing fab meals, and lots of places are doing it. Often cheaper than normal menu prices too.
