Bread Loses it's Status

Introduction

1. Bread of any size is HaMotzei, even if it's crumbled into small pieces.
2. There's three ways that bread can loose it's status of bread and become a food which requires Mezonot.

Cooked bread

1. Bread that was crumbled to a size of less than a Kezayit and also cooked in a liquid (as opposed to baking) it takes on the bracha of Mezonot.
2. In order to be considered cooked the pieces of bread have to be in a hot pot (at least Yad Soldet Bo) on the fire or at least a pot that was removed from the fire (Kli Rishon), however, if it was heated in a Kli Sheni (a pot from which hot water was poured from a pot that was on the fire) the bread isn't considered cooked and the bracha is HaMotzei.
3. If hot water that was poured from a pot that was on the the fire at one point, there's a doubt whether the bread is considered cooking and so in such a case one should make HaMotzei on real bread and eat it.
4. According to Ashkenazim who hold that Matzah is HaMotzei if one dips Matzeh in a Kli Sheni (a cup of coffee which was poured from the water heater) the bracha is still HaMotzei.

Fried bread

1. There's a doubt regarding bread which was crumbled to pieces smaller than a Kezayit that was fried there's a doubt whether the bracha is Mezonot or is HaMotzei. According to Sephardim, the bracha is Mezonot.
2. Matzah Brei, according to Ashkenazim who hold Matzeh is HaMotzei all year, if it's broken to pieces smaller than a Kezayit and then fried (with enough oil to give a taste to the Matzeh), there's a doubt about the bracha and so it should be eaten in a meal, however if it's deep fried the bracha is Mezonot. According to Sephardim, who hold that Matzah is HaMotzei on Pesach, Matzah Brei on Pesach has the bracha of Mezonot as Sephardim consider frying like cooking.
3. French Toast is usually HaMotzei because it remains in pieces larger than a Kezayit, however, if the bread is broken into small pieces and then fried, there's a doubt about the bracha and one should eat it in a meal.

Kneaded with a liquid

1. If the bread is crumbled and stuck together using a liquid and now has no look of bread is considered Mezonot.
2. Therefore, according to Ashkenazim who hold Matzah is HaMotzei all year, Matzah meal that was mixed with liquid is Mezonot.

Practical examples

1. Chocolate covered Matzah is HaMotzei according to Ashkenazim who hold that it's HaMotzei all year and according to Sephardim on Pesach then it's HaMotzei.
2. Matzah balls is Mezonot because they are crumbled and then cooked.
3. Challah Kugel which is made from pieces of challah and kneaded together (and the bread is unrecognizable) and then baked, if it was just kneaded with water, the bracha is HaMotzei, if it was made with water and a little oil, sugar, honey, or fruit juice, then there's a doubt as to it's proper bracha and so it should be eaten in a meal, and lastly, if it was made with a lot of sugar, oil, honey, or fruit juice then the bracha is Mezonot.
4. Matzah meal cakes are Mezonot when the dough was made from majority of sweeteners as opposed to water (as is the usual case).
