I had a great weekend, and I hope you guys did too.

Then I realized I was out of yeast, so I couldn't take advantage of the weekend to bake more bread.

I usually just thrown in whatever I have on hand, like vegetables, any kind of meat, and or sea food, all cutting it all into small dice.pieces.

Cold, day-old cooked rice works wonders in the fried rice, and I'm a dab hand at making it.

I usually just thrown in whatever I have on hand, like vegetables, any kind of meat, and sea food, all (cutting into small dicecubes / diced up).

- "Cutting" should actually be past tense, because otherwise you're implying that they are being cut as you put them in.

I ate the leftover loaves yesterday.

“The” is OK if you assume your readers know which leftovers you’re referring to (from an earlier post). Otherwise, you could say you “ate some leftover loaves of bread yesterday.”

Since loaves are often fairly large, this sounds like you ate a LOT of bread, so you might want to change “loaves” to “ciabatta,” assuming that’s what you’re referring to.

In casual writing, many people will begin a sentence with “so,” but all of my high school English teachers insisted it was wrong.

Cold, day-old cooked rice {works wonders in the| works well} in fried rice, and I'm a dab hand at making it.

“The” would be right if you’d mentioned fried rice before.

“Works wonders” seems like an odd choice of words here, as if you’re trying to repair something.

“Cut into small dice” is technically correct, but “dice” is much more common as a verb than a noun: “all diced finely.”

And I like to eat my fried rice with chili sauce.

This sounds like you add the chili sauce to the rice after you’ve finished cooking it, presumably as a condiment.
