Hi Helen and welcome,
What a great idea, I too get really bored of my dishes but love to improvise, only problem with that I never know the recipes of any of the better dishes…… During lockdown, I made quite a few Quinoa Salads with feta, tomatoes, olives etc. I also loved making Tuna Nicoise, a dish I never normally think of. The green beans and potatoes with olives and Tuna ( fresh or tinned) were great for me as I love strong flavours in my food. Now Autumn is here I am loving roasted veg with sweet potatoes, mushrooms, cauliflower, Peppers and courgettes but you can use any veg you prefer. I season it with chilli, paprika, olive oil and celery salt but you could use any spices you prefer, I have it with plain leaves such as spinach and rocket. Please share your favourites ! oh and another thing I love is chilli con carne, made with a good quality Aberdeen Angus mince or mixed pork and beef mince, this year I have been adding dark chocolate (70% plus)as well and sometimes also lentils, very filling but if you add lentils do adjust the amount of meat you add.
