Here's what I did as a solo:
Spitroast and dry fish - pretty much the entire game. Make spitroast alt(s) so you dont need to wait as long and can properly time the sizzle bonus. If you don't have the casting rod because it takes cloth and you are a noob - get clover and click sheep until you can make 1 cloth for it. This one item will carry you through the earlygame.
.1% hunger berries - dig the bushes up and bring them home quality does not matter. Variety is important obviously for the variety fep bonus. 16 bushes seems ok but depends on how much you gonna be eating, some bushes produce more than others too.
If you know what you are doing smoke specific meats, just spitroast if you don't know what you are doing. Smoking meat and not sausage is only for boar and other key early game meats that get a decent bonus/change when smoked.
Perch and pike are your first 2 best fish. Sturgeon and all the +int fish are good too.
Eat ***perched perch*** with yellow onion it gives everything you need. Eat ring of brodgar (baking). Eat pumpkin pie for early +str. Once you can boat hunt make meat dishes/spitroast out of boar for str. If you don't have a frying pan then get one and make pan seared fish/crackling cuts/***autumn steak***. Next step is to make minehole l2 and get bronze. Keep eating well and eventually you will be able to mine quickly.
You should have a decent farm going at this point too, doesn't need to be high quality can buy better seeds later on at a market, focus on quantity. At least q10 obviously.
As for drinks you should definitely get them asap at least q10. Milk/tea is usually first, followed by cider and perry, followed by wine/mead/beer. Imagine eating 20 perched perch with +50% satiation bonus.
With all of this you will be fine if you use your time wisely, just make sure you find a big flat place to live so you have space for all of the farming, trellises, and storage you need to do without much terraforming.
Also I don't recommend worrying about using bonfire. With the time it takes to get the wood and light it, and the tiny benefit it offers, and the swap to +cha gear for your alts, you were better off just making more food. Who cares about +1% bonus when you can get +50% bonus from beer. As a side note, has anyone done quality testing on the bonfires? It has quality when inspected so it might matter.
So yea as others have said just eat fish. Focus on foods that give stats for things you want to do based on how easy they are to make.
