If you don't want to use margarine, please use butter
Break the eggs into a bowl, add the sugar, and mix together until the sugar is dissolved. Add the milk and mix well.
Cut the bread slices into four pieces each. Next, put the bread into the bowl with the egg mixture until it has soaked it completely up.
Put about 1 tbsp of margarine into a frying pan and turn the heat to medium. When the butter has melted, arrange the bread from Step 2 in the pan and fry.
When it has a nice color, flip it. If the margarine has disappeared, you can put in a little margarine a bit at a time.
Story Behind this Recipe
So that even my junior high school student daughter can make it, "Mix everything in Step One" is an easy way to remember. If you use bread that has gone a little stale, you can kill two birds with one stone.
I wanted to have some french toast that was flavorful all the way to the center, so I used the thinner sliced bread from a 6-pack (a 5-pack is also okay) so it can absorb the egg mixture quickly. Use whatever kind of bread you like, but when you're busy, I recommend the 6-pack bread.
