SIS - Simple is Smart Tip
- If you don’t have purple potatoes use white or red fingerling potatoes. the fingerling potatoes work best as the cook in a shorter time and are done about the same time the cheese is crispy and golden brown.
- When a recipe calls for roasted garlic and you don’t have time to roast a head of garlic. Take a whole head of garlic and slice the top off of the garlic. Place the garlic cut side down in a microwave safe bowel. Add a Tbsp. of olive oil and 3 Tbsp of water to the bowl. Microwave on 50% power for 4 – 6 minutes or until the garlic cloves are soft. Pop out the cloves from the skins and use like roasted garlic or put them in a small container with a lid. Cover the cloves with olive oil and store them for up to 2 weeks in the refrigerator. After using up the stored garlic cloves use the garlic infused olive oil as a dip or brush veggies with it before roasting them.
