I live with my partner, but he travels with work a lot. We do eat meat, but I tend not to on my own. Staple meals for me are:
Jacket potato and salad - fillings like beans, cheese, coleslaw, tuna (you probably don’t eat tuna)
Pan fry gnocchi with pesto and peas
Stir fry veg with noodles - I buy bagged stir fry veg and split it over two nights
Scrambled eggs on toast. I add cheese/ham/cooked chorizo
Chickpea curry (make/freeze) with rice/naan. I do onion, garlic, peppers, carrrots, tin of chickpeas, paprika, cumin, tin of chopped tomatoes, simmer it down for as long as possible. Not very authentic but very tasty!
I often make soup on a Sunday with whatever is knocking about and have that with part-bake baguette from the supermarket
Mushrooms cooked in butter and garlic, stirred through pasta with a dollop of crème fraish or Philadelphia
Spicy Mexican rice (from a packet that goes in the microwave) with sliced avocado and a poached egg. If DP is here we often have this with chorizo
I am also partial to an M&S ready meal tbh
