Instructions
If you're using a frozen bag of green beans, heat them in the microwave for 3 minutes. If you're using fresh green beans, you can steam them for 10 minutes. Then set aside.
Heat 2 tbsp oil in a large pan on low-medium heat, and add garlic, onion, and fennel. Cook for about 4-5 minutes. Stir often.
Add 2 tbsp soy sauce and sliced red bell pepper. Cook for another 2 minutes.
Preheat oven to 375 degrees.
Add 3 tbsp flour and stir well to make a roux. Season with salt & pepper.
Keep stirring while adding 2 cups non-dairy milk (unsweetened & unflavored). Stir often until sauce is thickened. It could take about 10 minutes.
Add green beans and 1/2 cup fried onions. Stir until combined, and transfer it to a baking dish. Top the casserole with more fried onions (about 1 cup). Bake at 375 degrees for 20 minutes.
