I don't eat meat, but occasionally will eat fish. Most of my dinners are fairly quick and easy, more like lunch food than dinner - sometimes I just have a nice toasted sandwich if I'm not that hungry.
I batch cook lentil vegetable soup and butternut squash & sweet potato soup so have a few portions in the freezer for lunches/ dinners during the week.
I sometimes make my version of spanish omlette - fry some potatoes and onion in olive oil, add a few eggs (I add some garlic and cheese also), and finish under the grill. Serve with salad and coleslaw.
I also buy good quality pizza bases, and add loads of my own toppings (broccoli, spinach, red and yellow peppers, red onion, courgette, lots of cheese). Sounds weird but is delicious.
I freeze sourdough bread in slices so I just pop 2 in the toaster and add toppings (tuna and cheese melt, brie & tomato slices, or poached egg & avocado). Great for lunches or a quick dinner.
I also have nice veggie burgers in the freezer, which I bake and then add a fried egg on top - yum!
Also veggie stir-fry's with brown rice, or spinach and feta cheese parcels made with puff pastry - these freeze well and bake in about 30 mins.
