I feel you! On weekends, I make sure to allot my free time in feeding my family with the best recipes. My husband loves it each time I experiment on random ingredients. However, running out of ideas can't be avoided. Good thing I found this link online - http://panlasangpinoy.com/lunch-recipes/. Panlasang Pinoy's website helped me a lot. It has unique menu ideas that your family will surely like. It became my bible for cooking. As of to date, the site has 69 pages of lunch recipes and there are new updates everyday so no need to worry.
I agree with Johai. You can learn a lot of new recipes from Panlasang Pinoy. Their recipes are very much fit for the Pinoy taste buds. There's also http://www.filipinorecipesite.com/filipino-recipes with a detailed description of each dish and you can also download an app where you can prepare for a week's meal plan for the family.
BBQ will always be the best. Hotdogs, sausages, pork chops and ribs American style in short. Then match it with mashpo or steamed veggies. BBQ or grilling is safe in any occasion.
