Split peas contain 16 g
protein per serving, spinach has 13 and chickpeas have 8 g
protein/serving. Avocados have 1 g
protein per ounce. A medium peach has 2 g protein and 149 grams of dried figs have 5 g protein.
I love avocado smoothies, but avocados have a lot of calories, so you have to watch that. Peaches would be okay.
You can make a smoothie using soy milk, and sugar free chocolate pudding mix, but the only protein you'd get is from the soy milk.
