Use fresh ingredients if you want - for quick and easy use the following:
2 cups your favorite cooked rice
1 cup frozen chopped onions
1 - 10 oz package frozen spinach
salt, ground black pepper to taste
1/4-1/2 teaspoon nutmeg
chopped garlic if desired
1 can small black beans, rinsed and drained
1/4 cup toasted pine nuts
This is just a collection of variations on spinach with rice, with delicious results.
In a non-stick pan sprayed with olive oil, saute onion (and garlic) until golden. Add spinach and stir-fry until cooked through. Stir in seasonings and beans, then add rice and pine nuts and stir until heated through. (you could save a step by sauteing pine nuts with the onion but be careful not to burn them)
Without the beans, its a side dish. With the beans its a meal. Its good hot when fresh, or at room temperature for lunch the next day. It has several different textures that are a treat for your senses.
Vary the seasonings and beans according to your taste. Broccoli Rabe or other dark green leafy vegetable could be substituted for, or added to the spinach. Other good additions would be soy parmesan or mock crab.
