How to use && inside echo without using quotes?

I want to write a command like this inside a file using only cmd.exe (with ShellExecute, C++),

It's something like this:

timeout /t 10 && start cmd.exe /C "ssh -o ..."

I tried using this:

echo timeout /t 10 && start cmd.exe /C "ssh -o ..." > myfile.bat

but it cuts when it reaches && and I can't use quotes on the entire string, so what should I do? I don't want to use anything other than cmd.exe, and I just want to write this to a .bat file.

How can I solve this?

1) Use disappearing quotes.

FOR %%^" in ("") do (
    echo %%~"timeout /t 10 && start cmd.exe /C "ssh -o ..." %%~" > myfile.bat
)

2) Escape the special characters

echo timeout /t 10 ^&^& start cmd.exe /C "ssh -o ..." > myfile.bat

3) Use delayed expansion

setlocal EnableDelayedExpansion 
set "line=timeout /t 10 && start cmd.exe /C "ssh -o ...""
echo !line! > myFile
