TRY THIS DELICIOUS NEW “FLAVOR-SEAL” WAY TO COOK VEGETABLES

Measure 1 tablespoon MAZOLA Corn Oil into skillet or saucepan. Add seasonings and 1 package (10 oz.) frozen vegetables or 3 cups (about 1 lb.) prepared fresh vegetables, washed, drained, not dried.

Cover tightly. Cook on medium to low heat until just tender (8-12 minutes). Time varies with type and tenderness of vegetables.

During cooking, shake or move pan several times to prevent sticking. For starchy or stalky vegetables, add up to 3 tablespoons water. For frozen vegetables, turn frozen block frequently during first part of cooking, to thaw and break up.
