Your meals sound delicious and nutritious!
I also want to run myself headfirst into a wall when planning meals and the sheer fucking mundanity of it all.
What I found helps is keeping it as seasonal as possible and disregarding whatever recipe doesn't use the food in season. Then it's marginally less boring. So every 12 weeks I start a new rotation.
Spring is generally pea shoots, rocket, lambs lettuce, courgette, leek, new potatoes, figs, - late spring will be asparagus, wild garlic, broad beans, rosemary flowers - and meat/fish will be lamb chops & steak, chicken & sea bass & salmon - leaving behind the cheesy mash/mince/stews & casseroles of winter.
We are having variations of fig & goats cheese tart, chicken & leek pie, leek and potato soup, roast chicken with baby new potatoes & salad, lamb steaks with orzo & rocket, sea bass and parmentier potatoes with rosemary, peashoot & lambs lettuce salad with shaved goats cheese, salmon with courgette risotto & rocket
Then come late April/May it will be an overdose of asparagus & broad beans, peas mint & broccoli & spinach, wild garlic pesto etc
