Okay, here we have this:

Considering the provided information, we are going to calculate how many different meals are possible, so we obtain the following:

There are 11 ways to choose a main dish, 7 ways to choose a vegetable, 12 ways to choose the first dessert, and 11 ways to choose the second dessert. Then:

We multiply to find the possible number of combinations:


\begin{gathered} 11\cdot7\cdot12\cdot11 \\ =10164 \end{gathered}

Finally we obtain that there are 10164 different meals possible.
