I don’t know where to post this, so I’m posting it here.
I need to gain some weight because I’m borderline anorexic. But I can’t afford much more than bread, potatoes, eggs and cheese, That is my diet. And I hate eating it. It’s the only thing I can stomach that is cheap, but I hate it. I don’t want to eat eggs and potatoes for the rest of my life. I would rather die of malnutrition, like I am currently doing.
I have no appetite, but that is a symptom of something else. Ideally, there is a way to gain weight while eating less mass. Something calorie dense.
I might be slightly exaggerating. But for the last couple of years I’ve been eating potatoes and eggs for almost every single meal of the day. And yes, I eat one warm meal a day. Sometimes I suppliment with some bread to stop the hunger pains. Sometimes I also eat a piece of vegetable.


As someone who’s been cooking every meal with what is largely the same four to five ingredients for the past six months due to the economic situation here, I can say with confidence that varying preparation methods and spice profiles is key to thriving in spite of repetition.
Potatoes like the ones in your picture? Use them to make something akin to boxty: https://donalskehan.com/recipes/boxty-irish-potato-pancakes/
Unless you’re planning to make mash, though, you might benefit more from a method other than boiling your potatoes. Baking is far less effort and if you don’t feel like sticking them in the oven for an hour, you can microwave them for 6 minutes or so in a 1,000 watt microwave (if theyre still not soft, use more time).
What kind of bread are you working with?
Eggs, potatoes, cheese, and “bread” (traditionally tortillas, but wheat flour is wheat flour) are primary ingredients for a breakfast burrito. Splash of cumin, pinch of paprika, garlic powder, onion powder, and salt (maybe a tiny pinch of chili powder, cilantro, oregano, annato, and coriander if you have them, or lime juice, or tomato) if you can squish the bread flat and warm it in a pan a little you can slightly crisp up one side for texture and make an improv breakfast burrito sandwich.

Kitchens have been known to make potato cheese dumplings. Make the innards and serve as a spread on pan-fried (low heat) bread if you can’t make the dumpling exterior. (Edit – just saw that you said you’re from an eastern european country and I just recommended dumplings. LOL. That’s like asking an american if they’ve ever eaten a hot dog. I feel a tad silly. )

I’m sure someone has reccomended a Potato cheese omelette, but you can do those lots of ways, from a souffle omelete (separate eggs, whip the whites into stiff peaks, then fold in the yolks so it’s super fluffy) to gyeran-mari type rolled omelette https://www.koreanbapsang.com/gyeran-mari-korean-rolled-omelette/
Got sugar? Tired of eating bread in bread form?

I’ll edit the post to add more if I think of them, but I’m not awake yet.
Edit – just read your comment about the sugar tax. Boo :(
And about boiling being cheaper. (which is weird to me because boiling water is one of the most energy expensive methods of cooking when i go camping, but that might be due to wind, and as you said, circumstances are different in your area of the world, so boiling it is )
I saw rapeseed oil mentioned, got any other ingredients handy that you’re willing/able to use without causing family strife?
Even seemingly minor ingredients can make a big difference.
I’ll see what I can come up with for ideas.
