DD and I love bowl lunches. She likes grains as a base. Right now, we like quinoa, faro, couscous (the tiny kind and the pearl kind), and other small pasta shapes like orzo or ditalini. I like lettuce as a base and will just toss in a spoonful of whatever grain. We usually add chicken as a protein. We have a few main combos on repeat:
Southwest-ish
main ingredients: tomato, corn, black bean, cilantro, red onion, bell pepper
crunch: tortilla strips
dressing flavors: lime, cilantro
Mediterranean-ish
main ingredients: tomato, cucumber, feta, olives
sometimes add: bell pepper, chickpeas, white beans, red onion, marinated artichoke hearts
crunch: crushed pita chips
dressing flavors: lemon, oregano
Asian-ish
main ingredients: cucumber, carrot, green and/or purple cabbage, green onion
sometimes add: tofu instead of chicken, bell pepper
crunch: wonton strips, sliced almonds, sesame seeds
dressing flavors: sesame, soy sauce, rice wine vinegar
American steak house-ish
main ingredients: spinach, some kind of fruit (strawberry, raspberry, apple, grape), goat cheese
sometimes add: salmon instead of chicken, red onion (especially pickled)
crunch: some kind of nuts (pecan, hazelnut, walnut)
dressing: raspberry vinaigrette
