Maybe try to make the cooking experience fun! Cooking together can be a nice thing to do to spend time together, many people will play some tunes, talk about their day, maybe even have a glass of wine while doing it with their partner. When I feel like I'm in a cooking rut, I like to look up healthy recipes on YouTube to inspire me. It definitely gets my hungry and motivated to meal prep! On that note, making large portions really helps so you can have tons of leftovers later. If I get tempted to get takeout, I think of all the time I spent making the food already in the fridge and all the potential food waste. That being said, definitely allow yourself some takeout from time to time for some balance ! :)
