Combine milk and cooked lentils in blender and purée until smooth. Transfer to a saucepan and heat until warm to the touch, around 110°F (43°C), while stirring.
Transfer warm lentil/milk mixture to a large bowl and add in sugar, eggs, melted butter and combine well.
In another bowl, combine flour, yeast and salt and then add to the lentil/milk mixture and mix with a spoon until the dough begins to form a ball.
Transfer dough to a well-floured surface and knead for 6-7 minutes. The dough should be slightly sticky; if too sticky add a little more flour, a little at a time and work it in.
Transfer dough to a bowl that has been drizzled with canola oil, turn dough over to coat with oil then cover bowl with plastic wrap and a towel. Keep in a warm place until the dough has doubled in size, approximately 1 hour. Rise time may vary.
Once dough has risen, transfer to a floured work surface and roll out into a large, even rectangle, about 16-inches x 12-inches (40 cm x 30 cm).
Spread softened butter evenly over top of prepared dough.
In a small bowl, combine brown sugar, cranberries, pumpkin seeds, cinnamon, nutmeg and salt.
Sprinkle the mixture over the buttered section of the prepared dough and press the sugar mixture into the butter.
Roll the dough firmly starting from the shorter end. Gently press the seam into the dough to create a seal. Cut off about 1/2-inch (1 cm) from each end to remove excess dough.
Cut into 10 even rolls and place cut side up into a 10-inch x 13 1/2-inch (25 cm x 34 cm or similar) baking pan lined with parchment paper that has been sprayed with oil. Cover with plastic wrap and towel and allow to rise for 30 minutes, or until the rolls have doubled in size. While the rolls are rising, preheat the oven to 350°F (180°C).
Bake the rolls in preheated oven for 25-35 minutes, or until golden brown on top. Make frosting while cinnamon rolls are baking.
Allow to cool for 10 minutes, then spread the frosting evenly on top and enjoy!
Cream the softened cream cheese together with butter, icing sugar, salt, and vanilla until smooth. Spread on slightly cooled cinnamon rolls.
