You’ve probably already made your soup, and I hope you did add the frozen green beans. You can put them right into the boiling liquid, stirring to break up any clumps, and increasing the heat until the soup comes back to a boil before turning it down to simmer. Anything saucy works well with frozen veggies. If you’re going to make a fruit pie, it’s a good idea to use a recipe with specific directions, by adding “using frozen berries” or whatever to your search. But in general, I mix the sugar and cornstarch or other thickener and any spices in a bowl, and if the frozen fruit isn’t all stuck together I add it all at once and stir, then let it sit a few minutes and give it another stir before putting it in the crust. And I have foil ready for the crust edge in case the fruit is slow to cook through.

If the fruit or vegetables are frozen into a big lump, microwave a minute and break them up, but generally you want to use them a little icy.
