Basil season is coming, but it's not here yet. Meanwhile, other types of greens also make tasty pestos (and persuade my preschooler to scarf down leafy greens). The sunflower seeds here were a spur-of-the-moment inspiration upon looking into the pantry, and they are good, but you could also use more traditional nuts - pine nuts or walnuts.
5 oz arugula, washed
1/4 cup extra virgin olive oil
1/2 cup sunflower seeds, lightly toasted
1 large clove garlic
2 tsp lemon juice
1/3 cup grated Parmesan
Salt to taste
Combine all ingredients in a food processor and process until smooth. Taste and adjust seasonings if desired.
Serve immediately over pasta or hot new potatoes, or serve as a dip with pita chips.
Makes enough to sauce 1 lb cooked pasta.
