So lately I've been trying to gain weight, really just eating as much as I can of foods that aren't overwhelmingly unhealthy.

Rarely eat sweet things, try to stick to a lot of chicken, beef, fruit, vegetables, and bread, as well as a lot of bean & rice type dishes. Eggs and sausage in the morning and such with whatever is convenient for lunch and some type of meat for dinner.

Does anyone who actually knows what they're doing have any advice on what foods to eat to gain weight (in a balanced way ofc).

I'm doing a pretty mild workout right now that just consists of push-ups, sit-ups, dumbbells, and bench pressing. Going to buy a pullup bar soon and add that to the regiment.

Any advice on working out while gaining weight would be useful too.
