Eating healthy can raise questions such as "Are crayons a fruit or a vegetable?" and "How many steaks does a growing baby need?" Answer culinary questions with today's Groupon: for $25, you get $55 worth of healthy gourmet fare at Seventy @ Third, situated within the Westin Waltham Boston in Waltham.

Alongside expansive, expressive windows, Seventy @ Third forges gourmet flavors and opulent edibles with an eye on health and nutrition. The menu is geared toward nutrient- and antioxidant-rich superfoods like spinach, soy, and olive oil, allowing vitamin-conscious diners to promptly pick out nutrition powerhouses to strengthen stature, lengthen lives, and improve tentacle function. Let a fledgling meal take wing with a starter of pan-seared coastal crab cakes lain atop grilled spinach polenta and adorned with a tangy orange relish and basil oil ($17). Luxury lunchers can sate velvet-lined stomachs with an innovative creation, like the cumin-infused pulled-chicken tostada ($15.50), or the traditional treat of a flame-grilled bacon burger ($16.50). A serene fillet imparts fish-based wisdom to its soul-seeking veggie brethren of pan-roasted sweet potatoes and spinach in the broiled, green-tea-lacquered salmon with shiitake essence ($30.50), while a taste-tempting team of a char-grilled New York sirloin and rosemary sofrito bands together with whipped yukon gold potatoes and broccoli drizzled with lemon ($36).

The superfood-infused strawberry romanoff ends ornate eating adventures with a spike of sweetness and nutrition more satisfying than feasting on cartoon multivitamins ($9). Seventy @ Third opens at a sun-stealing 6:30 am.
