I say this as an Italian, because legend wants we love pasta and we all eat it every day almost religiously, pasta is the worst way to cook a quick and healthy meal in my opinion.

Sauce must be really good to enjoy pasta, pesto especially should be eaten fresh, it's true that here in Italy you can eat it at a fresh express pasta place for like 5-7 euros (more like 7-9 in a big city), it's not really that expensive, but still not that cheap either considering it's pasta, and cooking it at home requires a lot of preparation and attention IMO. You can't leave pasta unattended.

So here they are my go-to recipes for when I don't wanna be bothered:

- in summer: caprese salad, which is tomatoes + mozzarella + olive oil + basil + origan. you can add olives or capers if you like them, my favourite variant is with anchovies. Or you can have ham and melon. Or you can have mozzarella and ham and all the combinations you can think of: caprese + ham, caprese + melon, melon + mozzarella + ham etc. All of them take 5 minutes top to prepare, they're all delicious.

- fish: swordfish, tuna, mackerel, salmon, sardines etc. you can buy them steamed, grilled, smoked, marinated or in oil, they come in cans, jars or you can buy them at fresh food counters. not all of them come suuuper cheap, but they are usually affordable enough, and most of them are as cheap as pasta, especially the canned versions. you can heat some steamed/grilled mackerel fillet in the oven or in the microwave, add an herb sauce and it's like being at the restaurant.
also buying it fresh at the fish counter is an option, they prepare it for you so you don't have to and most of the time you just cook it in a pan for a few minutes in half a spoon of olive oil.

- everything with beans. I love beans, I could live just by eating beans every day of my life. my favourite kind is borlotti beans, you can eat them straight from the jar, we have a lot of high quality packaged beans which are also very cheap, like less than 1 euro for a 250 grams jar. My go-to recipe with beans is beans and tuna salad. It's simply borlotti beans + canned tuna + olive oil + some vinegar + some raw red onion. You can replace beans with your favourite legumes, for example chick-peas. you can also replace tuna with some other canned fish, like the aforementioned steamed or grilled mackerel.

- chicken: buy chicken breast, pound it a little bit and grill it for a few minutes, add olive oil and you're done. if you feel fancy, marinate it with some lemon juice, herbs and half a glass of white wine, put it in a covered glass bowl and leave it in the fridge over night. grill it at lunch the day after.

- caponata: which for the Italians who might read this, here I use as an umbrella term for a mix of vegetables. Take the vegetables you like, for example peppers, aubergines and zucchini. cut them into sorta like cube shaped pieces. put them in a pan, add olive oil, add some tomato sauce if you like it, cook it as much as the hardest vegetable requires, stir it from time to time.

what's really important in my opinion is cook/prepare your meals at least once a day. At least eat some food straight from the kitchen, if you are not the cook.
Avoid eating delivery/pre-cooked/processed food everyday.

You'll be doing something for yourself and you'll feel much better.

Take your time to cook for yourself but also for other people, it's never time wasted.
