vegetable casserole

My mom doesn't like green beans much so I put in other vegetables into the classic green bean casserole recipe to make it more appealing to her:)

step1
2 medium potatoes diced
1 carrot sliced or cubed
1 cup whole frozen/fresh green beans
1 stalk celery cubed
1 onion minced
4 cloves garlic minced
black pepper, salt, oregano, red pepper flakes
combine these in a bowl
step 2
1 tin condensed mushroom soup
1/2 cup 2% milk
mix these well and add to above mixture and stir
step 3
pour 1/2 mixture into casserole dish
layer with fried french onions or cheese
pour rest of mixture and top with either fried onions or cheese
bake 20-30 min @ 360 until potatoes are cooked
