Mood rings offer convenient color-coded glimpses into our emotional states: red indicates stress, yellow suggests blinding rage, and green means rich in vitamins, cellulose, and fiber. Adopt an avocado-hued demeanor with today’s Groupon: for $15, you get $30 worth of café fare at Silvergreens in Isla Vista and Santa Barbara.

Promoting healthful living through sustainable cooking practices and locally harvested ingredients, the chefs at Silvergreens occupy mandibles with an environmentally savvy omnibus of burgers, sandwiches, and vegetarian fare. An eclectic selection of juicy burgers served on wheat buns, such as the sundried tomato and avocado ($6.99) and pepper jack bacon ($6.79), regales bellies with tales of the outside world. Adorned with freshly sliced avocado, mozzarella, copious roughage, and homemade spread, the hummus delight sandwich ($7.69) showers tongues in chickpea confetti. A beverage and side of hand-cut fries provides loving support for lonesome entrees ($3.69), and smoothies ($3.79–$4.99) and all-natural frozen yogurt ($2.99) sing after meal lullabies to restless sweet teeth.

As eco-friendly as a steamboat that emits cloud kisses, Silvergreens makes use of biodegradable takeout bags and tabletops constructed from reclaimed eucalyptus trees.
