Will your family eat fish? Even if it's unfamiliar or they think they don't like it, you might try some really simple salmon recipes. Our whole family will eat these:
1) chop up a few cloves of garlic, and put that in a baking dish with a few tablespoons of soy sauce, a few tbs of orange juice or pineapple juice, or lemon juice and honey if you like, or just water. Lay salmon fillets in the marinade for a half hour or so (coat both sides). You can bake or broil these, depending on how thick they are.
2) another salmon recipe my family loves is also simple, although a little more fattening: use 1/2 stick melted butter, 3-4 chopped cloves of garlic, 1 TBS worcestershire sauce, and juice of 1 lemon. Stir this in a baking dish, and lay the salmon fillets in this (again, coat both sides). Bake at 350 till cooked through. This one is always a hit. MArinade also works great for shrimp.
3) Here is another recipe we like: you could substitute rice, or not eat any carbs if you don't want, with it:
Beans, Bowties, Spinach and Cheese
8 oz bowtie pasta
1 tbsp olive oil
3 garlic cloves, crushed/chopped
3 plum tomatoes, diced
1 can great northern beans (15 oz), drained and rinsed
¼ cup chicken broth
5 cups fresh spinach
¾ cups mozzarella cheese, shredded
½ cup parmesan cheese
Begin cooking pasta according to directions.
Meanwhile, heat oil in large skillet. Add garlic and tomatoes, and cook & stir about 2 minutes till soft.
Add beans, broth, and spinach. Cook until spinach wilts, stirring.
Season with salt and pepper.
Drain pasta, and add to skillet.
Add in cheeses, toss, and serve.
4) Here is a very simple chili that our family also eats -- very easy and fast, and tastes good:
(you can omit the pepper of course)
White Bean Chili
1 tablespoon olive oil
kosher salt and black pepper
1 large onion, chopped
1 green bell pepper, chopped
2 cloves garlic, chopped
1 teaspoon ground cumin
1 teaspoon chili powder
1 14.5-ounce can diced tomatoes
2 15-ounce cans cannellini (any white bean will work) beans, rinsed
Heat the oil in a large saucepan over medium-high heat. Add the onion and bell pepper and cook until tender, 6 to 8 minutes. Add the garlic, cumin, chili powder, 1 teaspoon salt, and ½ teaspoon pepper and cook until fragrant, 1 to 2 minutes.
Add the tomatoes and their liquid and 1½ cups water to the onion mixture; bring to a boil. Add the beans and simmer until slightly thickened, 8 to 10 minutes. Divide the chili among bowls and top with cooked bulgur (I didn't include this part because we never make the bulgur, but you can buy bulgur from the health food store and cook like rice).
I have lots more too, if you want :)
Good luck and enjoy!
