Greek Green Beans - cooking recipe

Ingredients

1 29 ounces canned green beans, drained or (16 ounce) package frozen green beans, cooked per pkg
1 (14 1/2 ounce) can of diced Italian tomatoes
1/2 teaspoon olive oil
1/2 1/2 cup fine chopped red onions or 1/2 cup any onion
1/2 teaspoon oregano
1/2 teaspoon lemon zest
1 tablespoon lemon juice
1/2 teaspoon minced garlic
1/4 cup crumbled feta cheese (or more)

Preparation

Cook your green beans fresh or frozen. If using canned skip this.
Heat the olive oil in a sauce pan, add the onions.
Cook until soft about 5 minutes on low.
Add everything but feta. If using canned green beans add now.
Simmer on low until hot.
Add feta.
I've done this in the oven in a casserole dish, and in a foil packet on the grill. You're basically just heating everything through.
