While pasta is cooking (rigatoni/penne or similar is best here), have a glass of wine.
3 minutes before it's ready, in a bowl mix a tub of ricotta, the zest of one lemon, a generous grating of parmesan, some garlic (I often just use garlic oil for convenience here), a drizzle of olive oil (if not using garlic oil) and some salt and Pepper.
1 minute before pasta is ready use a cup to scoop out roughly half a cup of the cooking water, then empty a bag of spinach in with the pasta.
Drain the pasta and spinach and replace in pot. Stir in the ricotta mix, using a bit of the hot cooking water to get it to dissolve a bit and spread out.
Serve with a squeeze of lemon juice, generous amount of fresh black pepper, grated parmesan and salt to taste.
My other option is a tiny bit more effort - but the bar is pretty low:
Slice courgettes. Fry slowly and gently in olive oil. Once softened, crank up heat, add lemon zest, chilli flakes and fresh garlic and let the courgettes brown slightly. Serve with feta cheese and season with lemon juice and salt to taste.
