In a medium pot, blanch green beans in a pot of boiling water for 2-3 minutes. Remove from pot and add to an ice bath to stop the cooking process of the beans.
Preheat oven to 450 degrees Fahrenheit.
In a large bowl, stir together milk, all-purpose seasoning, cumin, and soup until there are no lumps. Then, stir in minced garlic, sweet peppers, and onion.
Add green beans and half of the fried onions, then mix until combined.
Scrape the mix into an 8” baking pan and cover with the foil. Bake for 25 minutes.
Remove the foil and top with the remaining fried onions, then bake for 5 minutes.
