Healthy Skillet Cooking: Oil & Veggies for a Balanced Meal

Question
if I cook first oil and onion for seconds,
then I add meat and potatoes and others.
for health ,Is it good?

Answer
if you are talking about using oil to cook these items in a skillet, it is healthy, but I wouldn't eat it everyday. Oil is a very high fat food item. Use oils such as corn, safflower, and olive oil. Throw in some other veggies too! You can make vegetable stir fry! Don't be afraid to experiment with seasonings and sauces to change the flavor up!
